On the initial readthrough for my <a href=\"https:\/\/blogs.magicjudges.org\/nametherule\/uub-sos\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">update bulletin<\/a>, I noticed some issues with the design of these specific abilities, but the concept of intrinsic abilities seemed so straightforward that I didn&#8217;t give it a second thought.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This belief lasted right until I started typing the first sentence for that section of the bulletin; at that point, I realized that I had never seriously pondered how intrinsic abilities work, or read anything about that topic. One thing led to another and after crawling out of the rabbit hole, I had another eight thousand words on my hands. Enough material for a separate article, and the topic makes sense as a stand-alone article.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, here is my attempt at developing a proper rules set for intrinsic abilities.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"#all-questions-no-answers\">All questions, no answers<\/a><\/li>\n\n\n\n<li><a href=\"#related-rules-amendments\">Related rules amendments<\/a><\/li>\n\n\n\n<li><a href=\"#general-considerations\">General considerations<\/a><\/li>\n\n\n\n<li><a href=\"#layers-1-3\">Manipulation of intrinsic abilities in layers 1\u20133<\/a><\/li>\n\n\n\n<li><a href=\"#between-layers-3-and-4\">Between layers 3 and 4<\/a><\/li>\n\n\n\n<li><a href=\"#layers-4-7\">Manipulation of intrinsic abilities in layers 4\u20137<\/a><\/li>\n\n\n\n<li><a href=\"#the-system-so-far\">The system so far<\/a><\/li>\n\n\n\n<li><a href=\"#gaining-abilities-of-other-objects\">Gaining abilities of other objects<\/a><\/li>\n\n\n\n<li><a href=\"#miscellaneous-improvements\">Miscellaneous improvements<\/a><\/li>\n\n\n\n<li><a href=\"#proposed-amendments-to-the-comprehensive-rules\">Proposed amendments to the Comprehensive Rules<\/a><\/li>\n<\/ul>\n\n\n\n<h2 id=\"all-questions-no-answers\" class=\"wp-block-heading\">All questions, no answers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Comprehensive Rules (CR) have little to say about intrinsic abilities: the phrase appears seven times and each occurrence just states that a specific kind of object \u201chas the intrinsic ability [ability].\u201d But what does \u201cintrinsic\u201d mean? When does an object gain or lose such an ability? Is \u201cintrinsic\u201d a quality of an ability that can be identified by the rules\u2014or is an intrinsic ability, once gained, indistinguishable from \u201cregular\u201d abilities? How do intrinsic abilities fit into the layer system?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Comprehensive Rules contain no explicit answers, but an analysis of existing intrinsic abilities and relevant continuous effects yields a passable solution.<\/p>\n\n\n\n<h2 id=\"related-rules-amendments\" class=\"wp-block-heading\">Related rules amendments<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To solve issues I identified with the <em>Secrets of Strixhaven<\/em> update, I developed a couple of <a href=\"https:\/\/blogs.magicjudges.org\/nametherule\/pra-sos#sagas-and-initial-lore-counters\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">rules amendments<\/a>. The ones relevant for this article are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The two intrinsic abilities for Sagas with read ahead should be combined into one.<\/li>\n\n\n\n<li>The criteria for intrinsic Saga abilities should include having one or more chapter abilities.<\/li>\n\n\n\n<li>Rule <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3057\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">305.7<\/a> should remove all abilities of a land, including intrinsic abilities.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Besides solving the issues related to Sagas and their initial lore counters, these amendments also help with the rules for intrinsic abilities. I will point out whenever the differences between the actual Comprehensive Rules and my amendments become relevant.<\/p>\n\n\n\n<h2 id=\"general-considerations\" class=\"wp-block-heading\">General considerations<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before the <em>Secrets of Strixhaven<\/em> update, the Comprehensive Rules defined four intrinsic abilities:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>An object with a basic land type has the intrinsic ability \u201c{T}: Add [mana symbol].\u201d <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3056\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">[CR 305.6]<\/a><\/li>\n\n\n\n<li>A planeswalker has the intrinsic ability \u201cThis permanent enters with a number of loyalty counters on it equal to its printed loyalty number.\u201d <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3065b\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">[CR 306.5b]<\/a><\/li>\n\n\n\n<li>A battle has the intrinsic ability \u201cThis permanent enters with a number of defense counters on it equal to its printed defense number.\u201d <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3104b\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">[CR 310.4b]<\/a><\/li>\n\n\n\n<li>A Siege has the intrinsic ability \u201cWhen the last defense counter is removed from this permanent, exile it, then you may cast it transformed without paying its mana cost.\u201d <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R31012b\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">[CR 310.12b]<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In each case, an object needs to have a specific card type or subtype to gain the associated intrinsic ability. Three of the abilities are restricted to permanents, while the intrinsic mana ability applies to objects in any zone (and outside the game).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With the <em>Secrets of Strixhaven<\/em> update, there are two more intrinsic abilities\u2014three with the Comprehensive Rules as written. Unlike their predecessors, these intrinsic abilities also require the object to have or not have a specific ability (i.e. read ahead). As one might expect, this complicates matters slightly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the most basic scenario, where no continuous effects or other rules are involved, it does indeed suffice to say that an object \u201chas the intrinsic ability [ability].\u201d If Alex controls <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>, that permanent has a mana ability which Alex may activate. If <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon Blackblade<\/a> enters the battlefield under Alex\u2019s control, <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> has an intrinsic ability and enters the battlefield with four loyalty counters on it. The questions I asked at the start do not matter yet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s add <a href=\"https:\/\/gatherer.wizards.com\/TE\/en-us\/0\/humility\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Humility<\/a> to the scenario. If Alex controls <a href=\"https:\/\/gatherer.wizards.com\/TE\/en-us\/0\/humility\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Humility<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>, it should be unsurprising that <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> has no mana abilities. Likewise, if Alex controls <a href=\"https:\/\/gatherer.wizards.com\/TE\/en-us\/0\/humility\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Humility<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon Blackblade<\/a> enters the battlefield under Alex\u2019s control during her turn, the effect of <a href=\"https:\/\/gatherer.wizards.com\/TE\/en-us\/0\/humility\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Humility<\/a>\u2019s ability removes <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a>\u2019s intrinsic ability and <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> enters the battlefield with no loyalty counters on it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This simple scenario reveals the following point: for intrinsic abilities to interact intuitively with ability-removing effects, they cannot be applied to an object after its characteristic values have been determined (i.e. after layer 7). They need to be applied at an earlier point in the layer system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since the intrinsic abilities are all tied to a card type or subtype, this earlier point might be after type-changing effects have been applied and an object\u2019s types are final (i.e. after layer 4). This approach is also too simple, even without the Saga-specific abilities:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Alex controls <a href=\"https:\/\/gatherer.wizards.com\/ZNR\/en-us\/179\/ashaya-soul-of-the-wild\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Ashaya, Soul of the Wild<\/a> with a +1\/+1 counter on it and <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>. If <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon Blackblade<\/a> enters the battlefield under Alex\u2019s control during her turn, then the effect of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability applies to <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> and removes all its abilities. As a result, <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> should enter the battlefield with no loyalty counters on it. (Note that without an amendment to rule <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3057\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">305.7<\/a>, <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> would lose all abilities except for its intrinsic ability and still enter the battlefield with loyalty counters.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To achieve this outcome, intrinsic abilities cannot simply be added after layer 4. Doing so would give <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> the intrinsic planeswalker ability right back, since <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> is still a planeswalker after applying the effect of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adding intrinsic abilities somewhere before layer 4 takes care of the intrinsic planeswalker ability, but <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> should also gain an intrinsic mana ability each time a type-changing effect is applied in this scenario. In the end, <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> should have the intrinsic ability \u201c{T}: Add {R}\u201d and no other abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Point the second: If an object\u2019s unmodified characteristic values qualify for an intrinsic ability, the object must gain that ability before type-changing effects are applied.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Point three: There is no singular point at which to apply intrinsic abilities. Many effects that change an object\u2019s characteristic values may cause it to gain or lose intrinsic abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That last point should not be surprising, but to spell it out anyway: if an effect changes an object\u2019s characteristic values in such a way that they no longer match a specific intrinsic ability, the object should lose that ability. For example, if <a href=\"https:\/\/gatherer.wizards.com\/NEC\/en-us\/10\/swift-reconfiguration\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Swift Reconfiguration<\/a> becomes attached to <a href=\"https:\/\/gatherer.wizards.com\/RAV\/en-us\/284\/temple-garden\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Temple Garden<\/a>, the type-changing effect removes the two basic land types and <a href=\"https:\/\/gatherer.wizards.com\/RAV\/en-us\/284\/temple-garden\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Temple Garden<\/a> should lose its two intrinsic mana abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Point four: To be able to remove an intrinsic ability from an object that no longer meets its criteria, the ability must be identifiable as \u201cintrinsic.\u201d Thus, an intrinsic ability remains \u201cintrinsic\u201d while part of an object\u2019s characteristic values and can be identified as such.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conversely, an effect may change an object\u2019s characteristic values such that they qualify for a new intrinsic ability. For example, if <a href=\"https:\/\/gatherer.wizards.com\/PLC\/en-us\/165\/urborg-tomb-of-yawgmoth\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urborg, Tomb of Yawgmoth<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/RAV\/en-us\/284\/temple-garden\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Temple Garden<\/a> are on the battlefield, the type-changing effect of <a href=\"https:\/\/gatherer.wizards.com\/PLC\/en-us\/165\/urborg-tomb-of-yawgmoth\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urborg<\/a>\u2019s ability causes <a href=\"https:\/\/gatherer.wizards.com\/RAV\/en-us\/284\/temple-garden\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Temple Garden<\/a> to gain a third mana ability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach should not be too broad though. Going back to the scenario with <a href=\"https:\/\/gatherer.wizards.com\/TE\/en-us\/0\/humility\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Humility<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>, with the ability-removing effect applied, <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> has no abilities; it is still a Forest tough, so based purely on its characteristic values, it would still qualify for an intrinsic mana ability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Point five: An effect that changes an object\u2019s characteristic values should only cause a re-evaluation of its intrinsic abilities if the characteristic values are changed in a relevant way. Additionally, only specific intrinsic abilities should be re-evaluated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With \u201cre-evaluation,\u201d I mean removing the intrinsic ability if the object does not meet its criteria, or granting it the intrinsic ability if the object meets the criteria.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What is \u201crelevant\u201d? That must be determined by analyzing all the possible effects that may apply to objects; hopefully, a pattern emerges that translates to a set of simple rules.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Last but not least, an object should not end up with multiple instances of the same intrinsic ability. Which may be as simple as having a rule outright state that an object cannot have multiple instances of such an ability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now to go through the layer system and categorize all the relevant effects.<\/p>\n\n\n\n<h2 id=\"layers-1-3\" class=\"wp-block-heading\">Manipulation of intrinsic abilities in layers 1\u20133<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before the first layer, there are characteristic values derived from a card\u2019s printed text to consider (or for an object not represented by a card, the values it was created with). Those values may qualify the object for one or more intrinsic abilities. Applying the abilities at this point seems sensible: if there are no effects involved, the object has all the abilities it should have; if effects change the values in a relevant way, the intrinsic abilities can be changed at the same time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Layer 1: Modifications of copiable values<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Four things need to be considered here: classic copy effects, merged permanents, <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/80\/primal-plasma\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Primal Plasma<\/a> and similar cards, and face-down permanents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Copy effects are quite simple, as they give an object a complete set of characteristic values. These new values overwrite the old ones both mechanically and conceptionally\u2014the object\u2019s \u201cidentity\u201d is defined entirely by the new values. This should include intrinsic abilities: the copy effect overwrites any (intrinsic) abilities the object has and replaces them with the (intrinsic) ones copied from the template object.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if a copy effect causes <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> to become a copy of <a href=\"https:\/\/gatherer.wizards.com\/RAV\/en-us\/286\/watery-grave\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Watery Grave<\/a>, the copy effect overwrites the Forest land type and the associated intrinsic mana ability and replaces them with the Island and Swamp land types and the two associated mana abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A re-evaluation of all the object\u2019s intrinsic abilities is still necessary though, since the abilities copied onto the object may not be correct if the copy effect modifies the copied values in a relevant way.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if <a href=\"https:\/\/gatherer.wizards.com\/NEC\/en-us\/13\/imposter-mech\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Imposter Mech<\/a> enters the battlefield as a copy of <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>, the copy effect copies the Forest land type and the associated mana ability from <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>, then modifies these values by replacing Forest with artifact and Vehicle before applying them to <a href=\"https:\/\/gatherer.wizards.com\/NEC\/en-us\/13\/imposter-mech\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Imposter Mech<\/a>. The result of just the copy effect is that <a href=\"https:\/\/gatherer.wizards.com\/NEC\/en-us\/13\/imposter-mech\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Imposter Mech<\/a> is a Vehicle artifact with the intrinsic ability \u201c{T}: Add {G}.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This does not seem like the correct outcome to me: as a nonland permanent, <a href=\"https:\/\/gatherer.wizards.com\/NEC\/en-us\/13\/imposter-mech\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Imposter Mech<\/a> should not have an intrinsic mana ability. To correct this outcome, <a href=\"https:\/\/gatherer.wizards.com\/NEC\/en-us\/13\/imposter-mech\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Imposter Mech<\/a>\u2019s intrinsic abilities must be re-evaluated afterward.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This scenario also requires going back to the paragraph on pre-layer-1 characteristic values and making a slight adjustment. The part about \u201capplying the abilities\u201d should be \u201cre-evaluating all abilities,\u201d since copy effects may also affect those pre-layer values.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if the effect of <a href=\"https:\/\/gatherer.wizards.com\/REX\/en-us\/20\/dino-dna\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dino DNA<\/a>\u2019s second ability creates a token that\u2019s a copy of <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>, the token\u2019s defined characteristic values include the intrinsic ability copied from <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>, but not the Forest land type. A re-evaluation must be made to remove the intrinsic ability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Next are merged permanents, which in practice means the effect created by a resolving mutating creature spell merging with a permanent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the mutating creature spell becomes the permanent\u2019s topmost component, the effect sets the permanent\u2019s types to those of the new component, but allows it to retain all its old abilities. This may cause the mutated permanent to no longer meet the criteria of its intrinsic abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if Alex resolves <a href=\"https:\/\/gatherer.wizards.com\/IKO\/en-us\/37\/vulpikeet\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Vulpikeet<\/a> and merges it with <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>, putting <a href=\"https:\/\/gatherer.wizards.com\/IKO\/en-us\/37\/vulpikeet\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Vulpikeet<\/a> on top, the result of the \u201cmutate effect\u201d itself would be a Fox Bird creature with the intrinsic ability \u201c{T}: Add {G}.\u201d As before, this does not seem like the correct outcome and should cause a complete re-evaluation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the mutating creature spell becomes the bottommost component, it contributes its abilities to the resulting permanent, which makes no difference in practice; a re-evaluation can be performed, but won\u2019t change the permanent\u2019s intrinsic abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A card with mutate that also meets the criteria for an intrinsic ability remains theoretical for now. However, if such a card were the topmost component of a mutated permanent, the re-evaluation I already defined for a new topmost component should ensure that the permanent ends up with the correct intrinsic abilities. (Even more theoretically, the other components might have abilities that prevented the permanent from meeting the intrinsic ability\u2019s criteria; that too would be handled by the re-evaluation.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If that same hypothetical card became the bottommost component, the \u201cmutate effect\u201d would add only the component\u2019s \u201cprinted\u201d abilities, but not any intrinsic abilities. (The Comprehensive Rules are notoriously vague on the details of merged permanents, but I tend toward the card itself not having any intrinsic abilities while it is a component of the merged permanent.) If the added abilities made the permanent eligible for an intrinsic ability, it should gain that ability though. Again, a re-evaluation following the \u201cmutate effect\u201d would lead to the correct outcome.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, while most scenarios with mutated permanents are only theoretical, they all require or at least allow a complete re-evaluation after the \u201cmutate effect,\u201d which makes for a simple rule.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Next are replacement effects like that of <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/80\/primal-plasma\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Primal Plasma<\/a>\u2019s enters-the-battlefield ability. While most of these effects include setting the affected object\u2019s card type, I am unaware of a scenario where such an effect could apply to an object with an intrinsic ability. Still, if that were to happen, the changes made to the object\u2019s characteristic values should cause a re-evaluation of its intrinsic abilities, adding or removing abilities as appropriate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, there are changes due to a permanent\u2019s face-down status. These are like copy effects in that they overwrite all of a permanent\u2019s characteristic values, giving it a whole new \u201cidentity.\u201d After that identity change, intrinsic abilities should be completely re-evaluated (in case the permanent is face down due to the effect of <a href=\"https:\/\/gatherer.wizards.com\/C21\/en-us\/70\/yedora-grave-gardener\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Yedora, Grave Gardener<\/a>\u2019s ability).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Layer 2: Control-changing effects<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">While control of an object may become relevant in higher layers, control-changing effects themselves do not change an object&#8217;s qualities in a relevant way.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Layer 3: Text-changing effects<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">These effects become relevant in several ways, as text-changing effects can change the values of almost every characteristic. Notably, a text-changing effect cannot overwrite an object\u2019s intrinsic abilities on its own, since those are not derived from the object\u2019s rules text. (A subsequent re-evaluation might though.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, the only relevant effects are those that replace all instances of one basic land type with another and those that change an object\u2019s full text.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The former replace the basic land type in both the object\u2019s rules text and the text of its subtypes, which amounts to changing the object\u2019s land types.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> is affected by <a href=\"https:\/\/gatherer.wizards.com\/MI\/en-us\/0\/mind-bend\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mind Bend<\/a>\u2019s effect for which Alex chose to replace \u201cForest\u201d with \u201cSwamp,\u201d then the immediate result of <a href=\"https:\/\/gatherer.wizards.com\/MI\/en-us\/0\/mind-bend\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mind Bend<\/a>\u2019s effect is that <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> is a Swamp land with the intrinsic ability \u201c{T}: Add {G}.\u201d Its intrinsic abilities should be re-evaluated to align them with <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>\u2019s new land type.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a text-changing effect sets an object\u2019s full text, it overwrites almost all the object\u2019s characteristic values; one exception are abilities not derived from the object\u2019s rules text, such as intrinsic abilities. Still, this is another case of giving the object a new \u201cidentity,\u201d and any intrinsic abilities should be based on the new characteristic values.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if <a href=\"https:\/\/gatherer.wizards.com\/FIN\/en-us\/78\/summon-shiva\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Summon: Shiva<\/a> is the top card of Alex\u2019s graveyard as <a href=\"https:\/\/gatherer.wizards.com\/ST\/en-us\/0\/volraths-shapeshifter\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Volrath\u2019s Shapeshifter<\/a> enters the battlefield under her control, the text-changing effect of the ability of <a href=\"https:\/\/gatherer.wizards.com\/ST\/en-us\/0\/volraths-shapeshifter\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Volrath\u2019s Shapeshifter<\/a> gives it the full text of <a href=\"https:\/\/gatherer.wizards.com\/FIN\/en-us\/78\/summon-shiva\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Summon: Shiva<\/a>. The direct result of the effect is that <a href=\"https:\/\/gatherer.wizards.com\/ST\/en-us\/0\/volraths-shapeshifter\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Volrath\u2019s Shapeshifter<\/a> is a Saga with three chapter abilities, but with neither of the intrinsic Saga abilities; to rectify this, a re-evaluation should be performed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In another example, Alex controls <a href=\"https:\/\/gatherer.wizards.com\/ST\/en-us\/0\/volraths-shapeshifter\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Volrath\u2019s Shapeshifter<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>. She resolves <a href=\"https:\/\/gatherer.wizards.com\/UNF\/en-us\/45\/exchange-of-words\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Exchange of Words<\/a>\u2019s ability with <a href=\"https:\/\/gatherer.wizards.com\/ST\/en-us\/0\/volraths-shapeshifter\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Volrath\u2019s Shapeshifter<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> as the targets while she has no cards in her graveyard. Applying the effect created by that ability causes <a href=\"https:\/\/gatherer.wizards.com\/ST\/en-us\/0\/volraths-shapeshifter\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Volrath\u2019s Shapeshifter<\/a> to have no rules text and no abilities, while <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> has the printed rules text of <a href=\"https:\/\/gatherer.wizards.com\/ST\/en-us\/0\/volraths-shapeshifter\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Volrath\u2019s Shapeshifter<\/a>, the abilities derived from that rules text, and the intrinsic ability \u201c{T}: Add {G}.\u201d Dryad Arbor is still a Forest land, so the intrinsic ability is the desired outcome. Later, <a href=\"https:\/\/gatherer.wizards.com\/FDN\/en-us\/552\/bear-cub\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Bear Cub<\/a> becomes the top card of Alex&#8217;s graveyard. One of <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>\u2019s new abilities generates a text-changing effect which gives <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> the full text of <a href=\"https:\/\/gatherer.wizards.com\/FDN\/en-us\/552\/bear-cub\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Bear Cub<\/a>; with that effect applied, <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a> is a Bear creature with no rules text and no abilities other than the intrinsic ability \u201c{T}: Add {G}.\u201d To make <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbor<\/a>\u2019s intrinsic abilities match its new \u201cidentity,\u201d a re-evaluation should be performed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Text-changing effects may set an object\u2019s characteristic values in other ways, such as by changing its name, but those have no practical consequences for existing intrinsic abilities. The effect of <a href=\"https:\/\/gatherer.wizards.com\/UNF\/en-us\/45\/exchange-of-words\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Exchange of Words<\/a>\u2019s ability can influence a Saga\u2019s intrinsic ability, but not in a way that matters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if <a href=\"https:\/\/gatherer.wizards.com\/FIN\/en-us\/78\/summon-shiva\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Summon: Shiva<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/DMU\/en-us\/50\/founding-the-third-path\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Founding the Third Path<\/a> are affected by that effect, the direct result is that each Saga has the other\u2019s printed rules text and the abilities derived from that rules text, but each still has its \u201cnatural\u201d intrinsic ability. Re-evaluating both Sagas\u2019 intrinsic abilities corrects this, even if the specific abilities don\u2019t matter to Sagas already on the battlefield.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As in layer 1, should some other kind of text-changing effect ever become relevant in the future, the best choice seems to be a follow-up re-evaluation.<\/p>\n\n\n\n<h2 id=\"between-layers-3-and-4\" class=\"wp-block-heading\">Between layers 3 and 4<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With three layers done, an interesting pattern emerges. After applying an effect, a re-evaluation of all intrinsic abilities is either required or does not matter\u2014meaning that simply re-evaluating after each effect is a valid approach.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In other words, each time an effect sets an object\u2019s characteristic values, the new values (and only these values) should determine the object\u2019s intrinsic abilities. Whether the effect makes a meaningful change to the characteristic values is irrelevant\u2014if it doesn\u2019t, the new values lead to the same result as the old ones; if the change is meaningful, the new values should take precedence and the old values (and intrinsic abilities) be ignored.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a direct result, within layers 1\u20133, an object\u2019s intrinsic abilities and other characteristic values are always aligned: if the object meets an intrinsic ability\u2019s criteria, it has that ability; if it does not meet those criteria, it does not have that ability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since no intrinsic ability has an effect that applies in layers 1\u20133, a further simplification can be made: perform a single evaluation, after layer 3. That\u2019s it. Before that, no (re-)evaluation is required, since each effect is either irrelevant or obsoletes every (re-)evaluation made before it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(As a positive side effect, the awkward copying of intrinsic abilities goes away, as they are not part of an object\u2019s copiable values anymore. Intrinsic abilities are only part of an object\u2019s characteristic values in layers 4 and up.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This outcome is perhaps not so surprising if one considers the nature of those three layers. All of them perform rather \u201clow-level\u201d changes upon which the higher layers build. Copy effects and text-changing effects change the values of multiple characteristics at once, or even all of them, drastically altering the affected objects\u2019 appearance; meanwhile, effects from layers 4 and up only change one characteristic at a time. Copy effects and text-changing effects, together with control-changing effects, form the part of the layer system that yields an object\u2019s \u201cbase values,\u201d for lack of a better name.<\/p>\n\n\n\n<h2 id=\"layers-4-7\" class=\"wp-block-heading\">Manipulation of intrinsic abilities in layers 4\u20137<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Layer 4: Type-changing effects<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is where things get more complicated, because characteristic values and intrinsic abilities may diverge. Thanks to <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a> and similar cards.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most prominent example are <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a>. After layer 3, <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> is a Saga enchantment and has the intrinsic ability for Sagas without read ahead; intrinsic abilities and other characteristic values are aligned. Applying the effect of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability means that the land type of <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> changes from Urza\u2019s to Mountain, it loses all abilities (including intrinsic abilities), and it gains the intrinsic ability \u201c{T}: Add {R}\u201d <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3057\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">[CR 305.7]<\/a>. (Second reminder that rule <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3057\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">305.7<\/a> needs to be amended for this.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The effect\u2019s direct result is that <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> is a Saga enchantment without read ahead, but it does not have the associated intrinsic ability. Under my <a href=\"https:\/\/blogs.magicjudges.org\/nametherule\/pra-sos#sagas-and-initial-lore-counters\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">proposed amendment<\/a>, the intrinsic abilities would also require chapter abilities, so intrinsic abilities and other characteristic values would still match. Under the actual rules, intrinsic abilities and other characteristic values are misaligned.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this case, that is actually the desired outcome: <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> enters the battlefield with no lore counters on it. The major point of the <em>Secrets of Strixhaven<\/em> update was to enable this kind of interaction, even if it failed to achieve its goal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even under my amended rules, a misalignment can still happen with the other intrinsic abilities, whose criteria do not include abilities. See the example with <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/WAR\/en-us\/13\/gideon-blackblade\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Gideon<\/a> earlier on.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, a complete re-evaluation directly after the effect of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability is out of the question. In addition, any subsequent steps need to take that prior effect into account, meaning that a complete re-evaluation of intrinsic abilities cannot happen in any of the remaining layers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(From a technical perspective, the effect of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability and the effects from previous layers also show a clear difference in the way they modify the affected objects\u2019 characteristic values: all effects so far have overwritten the complete set of characteristics, including intrinsic abilities (e.g. copy effects), or have overwritten only the non-intrinsic parts, leaving the intrinsic abilities intact (e.g. the effect of <a href=\"https:\/\/gatherer.wizards.com\/MI\/en-us\/0\/mind-bend\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mind Bend<\/a>). Effects such as that of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability can overwrite the intrinsic abilities while leaving the non-intrinsic parts intact.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What other kinds of type-changing effects are there? In practice, there are effects that set a basic land type in addition to an object\u2019s existing types, e.g. <a href=\"https:\/\/gatherer.wizards.com\/SHM\/en-us\/126\/prismatic-omen\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Prismatic Omen<\/a>, and there are effects that set card types and subtypes other than basic land types, e.g. <a href=\"https:\/\/gatherer.wizards.com\/THB\/en-us\/59\/one-with-the-stars\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">One with the Stars<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike the effect of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability, neither kind removes intrinsic abilities directly, making them more like the effects of earlier layers. Still, the possibility of an earlier <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>-style effect prevents a complete re-evaluation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>, <a href=\"https:\/\/gatherer.wizards.com\/SHM\/en-us\/126\/prismatic-omen\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Prismatic Omen<\/a>, and <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> entered the battlefield under Alex\u2019s control in this order, <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> should enter the battlefield with five intrinsic mana abilities, but with none of the intrinsic abilities associated with Sagas. Therefore, after applying the effect of <a href=\"https:\/\/gatherer.wizards.com\/SHM\/en-us\/126\/prismatic-omen\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Prismatic Omen<\/a>\u2019s ability, only intrinsic mana abilities should be re-evaluated and other intrinsic abilities be ignored. (Third reminder about rule <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3057\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">305.7<\/a>.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Alex then attaches <a href=\"https:\/\/gatherer.wizards.com\/THB\/en-us\/59\/one-with-the-stars\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">One with the Stars<\/a> to <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a>. Applying the effect of that Aura\u2019s ability effectively removes the land card type and the five basic land types from <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a>, leaving it a Saga enchantment with five intrinsic mana abilities. Those mana abilities should also be removed, while the intrinsic abilities associated with Sagas should remain unchanged.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are no type-changing effects that set an object\u2019s card type to planeswalker or battle, or its subtype to Saga or Siege, which is hardly surprising. On their own, those types are not functional: they require additional abilities (e.g. chapter abilities), properties (e.g. being double-faced), and\/or characteristics\/counters (e.g. loyalty) to do anything useful. An effect that turns a permanent into a functional planeswalker, Saga, or battle would require a lot of words for not much gain, making it unlikely that Wizards of the Coast will ever print such a card. Still, new intrinsic abilities may be introduced in the future, and a bit of future-proofing never hurts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Essentially, such effects should follow the same rules as the existing ones: if a type-changing effect sets an object\u2019s card type or subtype, the object should gain each intrinsic ability associated with that card type or subtype, provided it meets any additional criteria; if a type-changing effect removes a card type or subtype, the object should lose each intrinsic ability associated with that card type or subtype. In both cases, other intrinsic abilities should be left as is.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, if an object becomes a planeswalker, a Saga, a battle, or one of the five basic land types due to a type-changing effect, it gains the associated intrinsic ability provided it meets that ability\u2019s other criteria. This should hold true even if the object already had that card type or subtype.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> were affected by the effect of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability and by an additional effect that set its types to a Saga enchantment, it should (re)gain an intrinsic ability due to that effect. (Under my <a href=\"https:\/\/blogs.magicjudges.org\/nametherule\/pra-sos#sagas-and-initial-lore-counters\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">amended rules<\/a>, <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> would gain no ability, because it still lacked its chapter abilities.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Notably, this preliminary rule applies only to type-changing effects that change relevant <em>types<\/em>. Generalizing this rule to type-changing effects that change <em>any<\/em> relevant characteristic would be incorrect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, Alex controls <a href=\"https:\/\/gatherer.wizards.com\/CG\/en-us\/13\/opalescence\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Opalescence<\/a>, <a href=\"https:\/\/gatherer.wizards.com\/ZNR\/en-us\/179\/ashaya-soul-of-the-wild\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Ashaya, Soul of the Wild<\/a> with a +1\/+1 counter on it, and <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>.

So, while the effect of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>\u2019s ability may have changed a relevant characteristic of <a href=\"https:\/\/gatherer.wizards.com\/DMU\/en-us\/50\/founding-the-third-path\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Founding the Third Path<\/a>, it did not change the right one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This concludes layer 4.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Layer 5: Color-changing effects<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Like layer 2, this layer holds nothing of interest.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Layer 6: Adding and removing abilities<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Naturally, this layer is relevant to intrinsic abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before the <em>Secrets of Strixhaven<\/em> update, this layer was much simpler, since intrinsic abilities had only card types or subtypes as their criteria. As such, ability-adding effects could be ignored entirely, and ability-removing effects removed any intrinsic abilities for good.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The new intrinsic abilities also check a Saga\u2019s abilities for read ahead, with one looking for its presence and one looking for its absence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, there are two kinds of effects to consider: effects that remove a permanent\u2019s abilities and effects that grant a permanent the read ahead ability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Handling effects that remove a permanent\u2019s abilities remains simple, since everything said about the ability-removing part of <a href=\"https:\/\/gatherer.wizards.com\/2XM\/en-us\/118\/blood-moon\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Blood Moon<\/a>-style effects should also apply here:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First, after removing an intrinsic ability from a permanent, if that ability does not depend on the permanent having a specific ability, the permanent still meets that intrinsic ability\u2019s criteria. However, re-applying that ability would clash with the nature of the ability-removing effect and be quite unintuitive, so no re-evaluation should take place.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Second, if the effect removes the abilities of a Saga with read ahead, that Saga becomes a Saga without read ahead; its characteristic values have changed in a relevant way and it is now eligible for another intrinsic ability, but the Saga should not gain that ability. So, no re-evaluation should take place. (Under my <a href=\"https:\/\/blogs.magicjudges.org\/nametherule\/pra-sos#sagas-and-initial-lore-counters\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">amended rules<\/a>, the intrinsic abilities would require chapter abilities, which the Saga has lost along with read ahead. Thus, the Saga would not be eligible for either ability; this would simplify the situation a bit.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In both cases, no re-evaluation regarding any intrinsic ability should be done after applying the ability-removing effect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Handling an effect that grants a Saga the read ahead ability should also be simple. If the Saga had no abilities before, it should gain the corresponding intrinsic ability under the actual rules, but not under my amended rules. If the Saga had the regular intrinsic ability before (and thus its chapter abilities), it should lose that ability and gain the other one under both sets of rules. If the Saga already had read ahead, nothing should change under either rules set.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In all three cases, performing a re-evaluation of the intrinsic Saga abilities after a Saga gains read ahead leads to the correct outcome, no matter the rules set.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With the two existing kinds of effects done, what hypothetical effects might one day exist?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An effect might remove only intrinsic abilities while leaving all other abilities intact. At a guess, this should remove most intrinsic abilities, but not those tied to the presence of a specific ability; a Saga with read ahead, for example, should have the associated intrinsic ability in the end. I expect that achieving this outcome would require a specific exception in the rules, and I do not see much potential in such an effect; therefore, I will ignore it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An effect might remove chapter abilities but leave intrinsic abilities and read ahead intact. Under my amended rules, an affected Saga would lose any intrinsic Saga ability it has, while under the actual rules, the Saga would keep its intrinsic abilities. I do not see much potential in such an effect either, but it should be easier to implement: the effect could be classified as an ability-changing effect that changes a relevant ability (the same as the existing effect that grants a Saga read ahead).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The candidate that has the most potential for me would be an effect that removes only the read ahead ability; the likely design goal of such an effect would be to turn Sagas with read ahead into \u201cregular\u201d Sagas. In that case, a Saga that loses only read ahead should lose the corresponding intrinsic ability and gain the other ability. This effect could be treated identically to the previous one: it\u2019s an ability-changing effect that changes a relevant ability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are more things to consider about ability-adding effects, which I discuss in a later section. Before that, a brief look at layer 7 and a recap.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Layer 7: Power- and\/or toughness-changing effects<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This layer holds nothing of interest. None of the intrinsic abilities rely on specific power and\/or toughness values (which makes sense, given the structure of the layer system) and effects in this layer cannot manipulate types or abilities.<\/p>\n\n\n\n<h2 id=\"the-system-so-far\" class=\"wp-block-heading\">The system so far<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here is what I determined so far:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>An object may gain and\/or lose intrinsic abilities at multiple points in the layer system.<\/li>\n\n\n\n<li>If an object gains an intrinsic ability, that ability has the \u201cintrinsic\u201d quality and rules can refer to that quality.<\/li>\n\n\n\n<li>An object cannot have multiple instances of the same intrinsic ability.<\/li>\n\n\n\n<li>An object\u2019s intrinsic abilities and its other characteristic values can match or they can be mismatched.\n<ul class=\"wp-block-list\">\n<li>Most of the time, an object\u2019s intrinsic abilities and its other characteristic values match.<\/li>\n\n\n\n<li>If an effect causes the object to lose its abilities, intrinsic abilities and other characteristic values may no longer match: the object may lack an intrinsic ability despite meeting its criteria.<\/li>\n\n\n\n<li>The other mismatch, where an object has an intrinsic ability without meeting its criteria, should never happen.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Layers 1\u20133:\n<ul class=\"wp-block-list\">\n<li>Each effect is either irrelevant for intrinsic abilities or it invalidates any prior determination of them.<\/li>\n\n\n\n<li>No intrinsic ability generates an effect that would apply in layers 1\u20133.<\/li>\n\n\n\n<li>A very simple solution presents itself: make the first determination of intrinsic abilities after layer 3 and before layer 4. Within layers 1\u20133, there are no intrinsic abilities.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Layer 4:\n<ul class=\"wp-block-list\">\n<li>After a type-changing effect sets the card type or subtype of an object, re-evaluate any intrinsic ability tied to that card type or subtype.<\/li>\n\n\n\n<li>After a type-changing effect removes a card type or subtype from an object, remove any intrinsic ability tied to that card type or subtype.<\/li>\n\n\n\n<li>A type-changing effect that sets a basic land type also removes all intrinsic abilities. (Fifth reminder about amending rule <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R3057\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">305.7<\/a>.)<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Layer 6:\n<ul class=\"wp-block-list\">\n<li>After an ability-adding effect grants an object an ability, re-evaluate any intrinsic ability tied to that ability.<\/li>\n\n\n\n<li>After an ability-removing effect removes a specific ability (rather than removing all abilities), re-evaluate any intrinsic ability tied to that ability.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">That doesn\u2019t seem too bad. Time to make it more complicated.<\/p>\n\n\n\n<h2 id=\"gaining-abilities-of-other-objects\" class=\"wp-block-heading\">Gaining abilities of other objects<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The part about intrinsic abilities being recognizable as such and the part that restricts an object to no more than one instance of each ability need some refinement. Specifically, these things should hold true only when the <em>rules<\/em> grant those abilities. If an ability-adding effect adds them, the granted abilities should be treated as normal, non-intrinsic abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if Alex controls <a href=\"https:\/\/gatherer.wizards.com\/C17\/en-us\/41\/mairsil-the-pretender\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mairsil, the Pretender<\/a> and she owns four <a href=\"https:\/\/gatherer.wizards.com\/TSR\/en-us\/277\/dryad-arbor\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dryad Arbors<\/a> in exile with cage counters on them, <a href=\"https:\/\/gatherer.wizards.com\/C17\/en-us\/41\/mairsil-the-pretender\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mairsil<\/a> should have four instances of \u201c{T}: Add {G}.\u201d Each instance could be activated once each turn, allowing Alex to produce up to four {G} each turn (provided she can also untap <a href=\"https:\/\/gatherer.wizards.com\/C17\/en-us\/41\/mairsil-the-pretender\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mairsil<\/a>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If Alex also controls <a href=\"https:\/\/gatherer.wizards.com\/ZNR\/en-us\/179\/ashaya-soul-of-the-wild\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Ashaya, Soul of the Wild<\/a>, <a href=\"https:\/\/gatherer.wizards.com\/C17\/en-us\/41\/mairsil-the-pretender\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mairsil<\/a> should have five instances of the mana ability. One instance should be an intrinsic ability tied to <a href=\"https:\/\/gatherer.wizards.com\/C17\/en-us\/41\/mairsil-the-pretender\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mairsil<\/a>\u2019s Forest land type and could be activated multiple times each turn; the other four should not be intrinsic abilities and could be activated only once each turn.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, with this kind of ability-adding effect, an object can gain the intrinsic abilities of another object without meeting the criteria of those abilities. And of course, the object should get to keep those abilities, rather than losing them immediately. Otherwise, cards like <a href=\"https:\/\/gatherer.wizards.com\/ONE\/en-us\/232\/mirran-safehouse\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mirran Safehouse<\/a> or <a href=\"https:\/\/gatherer.wizards.com\/TDC\/en-us\/48\/steward-of-the-harvest\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Steward of the Harvest<\/a> would behave quite unintuitively.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, trying to maintain the granted abilities\u2019 intrinsicness would require exceptions for practically everything where intrinsicness matters. The simpler solution is to declare abilities granted by an ability-adding effect as non-intrinsic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This also makes some sense conceptually: an object is supposed to gain predefined intrinsic abilities for its (more or less) inherent characteristic values, via game rules. Cards like <a href=\"https:\/\/gatherer.wizards.com\/C17\/en-us\/41\/mairsil-the-pretender\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mairsil<\/a>, on the other hand, do not rely on gifts from the rules; they use effects to acquire whatever abilities they can find.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The obvious follow-up question is: are there other effects that might distribute intrinsic abilities to other objects? Of course there are.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Text-changing effects, thankfully, are safe. Intrinsic abilities are not derived from rules text and thus cannot be (directly) overwritten, exchanged, removed, or otherwise be affected by text-changing effects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Copy effects can copy abilities that are not derived from rules text, provided the abilities are part of an object\u2019s copiable values. Which makes most copy effects safe, because in my system, intrinsic abilities are introduced only after layer 3 and as such should never be part of any copiable values.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Enter <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima of a Thousand Faces<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many copy effects add a specific ability to the copied values before applying them to the copy. This unique copy effect takes whatever abilities a specific object (i.e. <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>) may have, and adds them to the copy\u2019s new values. Since those abilities are not copied, the effect is not restricted to just abilities found in <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s copiable values\u2014any ability is fair game, no matter the layer in which it gets added to <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if Alex controls <a href=\"https:\/\/gatherer.wizards.com\/GU\/en-us\/35\/levitation\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Levitation<\/a> and <a href=\"https:\/\/gatherer.wizards.com\/FDN\/en-us\/552\/bear-cub\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Bear Cub<\/a> as <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> enters the battlefield under her control, Alex can choose to have <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> enter the battlefield as a copy of <a href=\"https:\/\/gatherer.wizards.com\/FDN\/en-us\/552\/bear-cub\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Bear Cub<\/a>, except that <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> also has <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s other abilities. Which, under rule <a href=\"https:\/\/yawgatog.com\/resources\/magic-rules\/#R61412\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">614.12<\/a> are the one concerning the \u201clegend rule,\u201d partner, and flying. Once on the battlefield, with all effects applied, <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> would then have two instances of flying, one as part of its copiable values, and the other from the ability-adding effect of <a href=\"https:\/\/gatherer.wizards.com\/GU\/en-us\/35\/levitation\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Levitation<\/a>\u2019s ability. And if <a href=\"https:\/\/gatherer.wizards.com\/GU\/en-us\/35\/levitation\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Levitation<\/a> leaves the battlefield, <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> still has one instance of flying.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(Another consequence of the copy effect\u2019s unique wording is that <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> can accumulate an arbitrary number of abilities if another <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> is already on the battlefield. The new <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> can repeatedly copy the old one and each time gain another instance of each of its abilities. And while five hundred instances of flying are not particularly powerful, five hundred instances of <a href=\"https:\/\/gatherer.wizards.com\/RVR\/en-us\/217\/rhythm-of-the-wild\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">riot<\/a> certainly are.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This quirk allows <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> to transport abilities from higher layers into layer 1, so to speak. What if one of those abilities is an intrinsic ability, say from the effect of <a href=\"https:\/\/gatherer.wizards.com\/ZNR\/en-us\/179\/ashaya-soul-of-the-wild\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Ashaya, Soul of the Wild<\/a>\u2019s ability? Should the ability that is now part of <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s copiable values be an intrinsic ability? If so, a number of follow-up questions arise. Does <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> keep that ability or is it removed by a re-evaluation? When is it removed? And if it stays, <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> should presumably not gain a second instance of that intrinsic ability when applying the effect of <a href=\"https:\/\/gatherer.wizards.com\/ZNR\/en-us\/179\/ashaya-soul-of-the-wild\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Ashaya<\/a>\u2019s ability in layer 4.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(Another solution would be to give <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> an erratum, such that the copy effect adds not \u201c<a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s other abilities,\u201d but \u201cThe \u2018legend rule\u2019 doesn\u2019t apply to permanents you control.\u201d A functional erratum, to be sure, but one that preserves what I think is the card\u2019s intended functionality. Then again, if that were the intended functionality, Wizards of the Coast would have used the proposed wording from the beginning, rather than creating this rogue. Also, such errata are kind of a cop-out from my perspective.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Personally, I prefer to treat this ability as intrinsic and thus subject to the model developed above. While the copy effect combines elements of a copy effect with an ability-adding effect, it ultimately is a copy effect and applied in layer 1. In scenarios like the one with <a href=\"https:\/\/gatherer.wizards.com\/NEC\/en-us\/13\/imposter-mech\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Imposter Mech<\/a>, acquiring an intrinsic ability via a copy effect does not work out if the copy\u2019s new values do not support the ability. <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s case feels similar enough.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now, how or when should this intrinsic ability be removed from <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s characteristic values?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Option one would be a re-evaluation after the effect, but how to write an elegant rule that captures only <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>? Approaching this from the other side, a rule that performs a re-evaluation after each (copy) effect would be simple enough to write, but result in many unnecessary checks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Option two would be to leave the rules as is, so that the check after layer 3 takes care of the ability. As a side effect, the intrinsic ability would be part of <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s characteristic values for the rest of layers 1\u20133, so other copy effects could copy that intrinsic ability. Those abilities would also be removed by the post-layer-3 re-evaluation, so everything still leads to the same outcomes; however, copying abilities for no ultimate purpose is something my model tries to avoid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The option I like best is to not acquire the ability in the first place: if the effect ignores <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s intrinsic abilities when determining the list of \u201c<a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a>\u2019s other abilities,\u201d the problem solves itself. The copy effect does not grant <a href=\"https:\/\/gatherer.wizards.com\/CMR\/en-us\/89\/sakashima-of-a-thousand-faces\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sakashima<\/a> any intrinsic abilities, so nothing needs to be re-evaluated and layers 1\u20133 stay free of intrinsic abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I admit there are several viable solutions for this issue, and a stronger focus on the \u201cability gaining\u201d aspect might move an ability into non-intrinsic territory. I just prefer to keep intrinsic abilities away from layers 1\u20133.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, the two points coming out of this section are as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If an ability-adding effect grants one or more abilities to one or more objects based on the abilities of some (other) object, the granted abilities are not intrinsic, even if the corresponding abilities of the source object are.<\/li>\n\n\n\n<li>If any other kind of effect adds to or sets the abilities of an object based on the abilities of some (other) object, intrinsic abilities among those abilities are ignored. The same is true if the effect defines the characteristic values of a token.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">(That last sentence is for <a href=\"https:\/\/gatherer.wizards.com\/AFR\/en-us\/91\/the-book-of-vile-darkness\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">The Book of Vile Darkness<\/a>. Currently, the only intrinsic ability that is a triggered ability exists only on the battlefield, but better safe than sorry.)<\/p>\n\n\n\n<h2 id=\"miscellaneous-improvements\" class=\"wp-block-heading\">Miscellaneous improvements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Two last things before writing out the rules for intrinsic abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First, the pre-<em>Secrets of Strixhaven<\/em> abilities were all created before <em>Magic: The Gathering Foundations<\/em> introduced the current <a href=\"https:\/\/blogs.magicjudges.org\/nametherule\/this-object\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">guidelines for self-references in card text<\/a>. The text of these intrinsic abilities should be updated to match the guidelines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Second, my <a href=\"https:\/\/blogs.magicjudges.org\/nametherule\/pra-sos#sagas-and-initial-lore-counters\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">proposed amendment<\/a> of adding chapter abilities to the criteria of intrinsic Saga abilities allows for a further simplification: combining both abilities into one. Any Saga with chapter abilities would have the same intrinsic ability along the lines of \u201cAs this Saga enters, if it has read ahead, choose a number between one and this Saga\u2019s final chapter number. This Saga enters with the chosen number of lore counters on it. If it doesn\u2019t have read ahead, it enters with a lore counter on it.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Obviously, this ability would be longer than each of the separate abilities on its own; however, the text appears only in the rules and not on cards, so length is less of an issue. And complexity-wise, it remains perfectly understandable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The benefit I gained from this change is that the ability becomes easier to apply in certain situations. Two separate abilities, one with a negative condition (i.e. not having read ahead), were more complex whenever a Saga loses one of them\u2014it should not automatically gain the other one and I had to decide on the correct answer each time. How a Saga should behave if it loses read ahead also proved more complex with two abilities. Last but not least, it made writing the rules a bit easier (see below).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(Note that without the addition of chapter abilities to the criteria, the intrinsic abilities cannot be combined quite so elegantly because the only remaining criterion would be \u201ca Saga.\u201d This would cause an issue if a Saga without any abilities gains read ahead: as long as read ahead is part of the criteria, gaining read ahead is a relevant change and causes a re-evaluation; if read ahead only appeared in the intrinsic ability\u2019s text, the rules would need to check that text for any abilities mentioned to recognize the change as relevant.

Note that this version is written for a single intrinsic Saga ability that requires the Saga to have chapter abilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With two separate abilities, rule 608.3g would lead to the wrong outcome in the <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> plus <a href=\"https:\/\/gatherer.wizards.com\/WHO\/en-us\/14\/barbara-wright\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Barbara Wright<\/a> scenario: <a href=\"https:\/\/gatherer.wizards.com\/MH2\/en-us\/259\/urzas-saga\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Urza\u2019s Saga<\/a> would gain the intrinsic ability tied to having read ahead, but it would not lose the intrinsic ability tied to not having read ahead. To rectify this, rule 608.3g would need to also remove abilities whose criteria are no longer met.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Similarly, the hypothetical scenario of an effect removing just read ahead is not covered correctly by rule 608.3h when using the actual intrinsic abilities: the Saga would lose read ahead and its intrinsic ability, but not gain the \u201cdefault\u201d intrinsic ability. Rule 608.3h would need to also grant abilities whose criteria are now met.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Last but not least, \u201can ability [\u2026] that is part of an intrinsic ability\u2019s criteria\u201d might be misconstrued to mean only the presence of an ability, but not the absence of an ability.
