They are written as \u201c<strong>[trigger condition], [effect]<\/strong>\u201d, and begin with the expression \u201c<strong>When<\/strong>\u201d, \u201c<strong>Whenever<\/strong>\u201d or \u201c<strong>At<\/strong>\u201d. They may also be expressed as <strong>\u201c[When\/Whenever\/At]<\/strong> <strong>[trigger event], [effect]<\/strong>\u201d.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline\"><strong>TRIGGER CONDITION<\/strong><\/span><\/p>\n<p>Whenever a game event or game state matches a triggered ability\u2019s trigger event, that ability automatically triggers. The ability doesn\u2019t do anything at this point.<\/p>\n<p>When a phase or step begins, all abilities that trigger \u201cat the beginning of\u201d that phase or step trigger. An ability triggers only once each time its trigger event occurs. However, it can trigger repeatedly if one event contains multiple occurrences.<\/p>\n<p>Some trigger events use the word \u201cbecomes\u201d; for example, \u201cbecomes attached\u201d or \u201cbecomes blocked\u201d. These trigger only at the time the named event happens. They don\u2019t trigger if that state already exists or retrigger if it persists. An ability that triggers when a permanent \u201cbecomes tapped\u201d or \u201cbecomes untapped\u201d doesn\u2019t trigger if the permanent enters the battlefield in that state.<\/p>\n<p>If a triggered ability\u2019s trigger condition is met, but the object with that triggered ability is at no time visible to all players, the ability does not trigger.<\/p>\n<p>Because they are not casted or activated, triggered abilities can trigger even when it is not legal to cast spells or activate abilities.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline\"><strong>STACK PLACEMENT AND CONSIDERATIONS<\/strong><\/span><\/p>\n<p>Once an ability has triggered, its controller puts it on the stack as an object that\u2019s not a card <strong>the next time a player would receive priority<\/strong>.<\/p>\n<ul>\n<li>The ability becomes the topmost object on the stack.<\/li>\n<li>It has the text of the ability that created it, and no other characteristics.<\/li>\n<li>It remains on the stack until it\u2019s countered, it resolves, a rule causes it to be removed from the stack, or an effect moves it elsewhere.<\/li>\n<\/ul>\n<p>A triggered ability is controlled by the player who controlled its source at the time it triggered.<\/p>\n<p>If multiple abilities have triggered since the last time a player received priority:<\/p>\n<ol>\n<li>If multiple abilities have triggered since the last time a player received priority, each player, in APNAP order (Active Player \u2013 Non Active Player), puts triggered abilities he or she controls on the stack. If a player has several abilities to put on the stack, that player can place them in any order of his or her choice.<\/li>\n<li>The game once again checks for and resolves state-based actions until none are performed.<\/li>\n<li>Abilities that triggered during this process go on the stack.<\/li>\n<li>This process repeats until no new state-based actions are performed and no abilities trigger.<\/li>\n<li>Then the appropriate player gets priority.<\/li>\n<\/ol>\n<p>If a triggered ability is modal, its controller announces the mode choice when he or she puts the ability on the stack. If one of the modes would be illegal (due to an inability to choose legal targets, for example), that mode can\u2019t be chosen. If no mode can be chosen, the ability is removed from the stack.<\/p>\n<p>The remainder of the process for putting a triggered ability on the stack is identical to the process for casting a spell. If a choice is required when the triggered ability goes on the stack but no legal choices can be made for it, or if a rule or a continuous effect otherwise makes the ability illegal, the ability is simply removed from the stack.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline\"><strong>CONDITIONAL TRIGGERED ABILITIES<\/strong><\/span><\/p>\n<p>A triggered ability may read \u201cWhen\/Whenever\/At [trigger event], <strong>if [condition]<\/strong>, [effect]\u201d.<\/p>\n<p>The part of the <strong>if [condition]<\/strong> is a condition that must be fulfilled in addition to the trigger event for the ability to be put on the stack. When the trigger event occurs, the ability checks whether the stated condition is true. The ability triggers only if it is; otherwise it does nothing.<\/p>\n<p>If the ability triggers, it checks the stated condition again as it resolves. If the condition isn\u2019t true at that time, the ability is removed from the stack and does nothing. Note that this mirrors the check for legal targets. This rule is referred to as the \u201cintervening \u2018if\u2019 clause\u201d rule. This rule only applies to an \u201cif\u201d that immediately follows a trigger condition.<\/p>\n<p>Thus, as a summary, the condition is verified in two moments:<\/p>\n<ol>\n<li>When it\u2019s going to be put on the stack.<\/li>\n<li>When it will be resolved.<\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline\"><strong>OPTIONAL TRIGGERED ABILITIES<\/strong><\/span><\/p>\n<p>Some triggered abilities\u2019 effects are optional (they contain \u201cmay\u201d, as in \u201cAt the beginning of your upkeep, you may draw a card\u201d). These abilities <strong>go on the stack when they trigger, regardless of whether their controller intends to exercise the ability\u2019s option or not<\/strong>.<\/p>\n<p>The <strong>choice<\/strong> is made <strong>when the ability resolves<\/strong>. Likewise, triggered abilities that have an effect \u201cunless\u201d something is true or a player chooses to do something will go on the stack normally; the \u201cunless\u201d part of the ability is dealt with when the ability resolves.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline\"><strong>ZONE-CHANGE AND ENTER\/LEAVES THE BATTLEFIED ABILITIES<\/strong><\/span><\/p>\n<p>Trigger events that involve objects changing zones are called \u201czone-change triggers.\u201d Many abilities with zone-change triggers attempt to do something to that object after it changes zones. During resolution, these abilities look for the object in the zone that it moved to. If the object is unable to be found in the zone it went to, the part of the ability attempting to do something to the object will fail to do anything. The ability could be unable to find the object because the object never entered the specified zone, because it left the zone before the ability resolved, or because it is in a zone that is hidden from a player, such as a library or an opponent\u2019s hand. (This rule applies even if the object leaves the zone and returns again before the ability resolves.) The most common zone-change triggers are enters-the-battlefield triggers and leaves-the-battlefield triggers.<\/p>\n<p><strong><u>Enters the Battlefield:<\/u><\/strong><\/p>\n<p><strong>Enters-the-battlefield<\/strong> abilities trigger <strong>when a permanent enters the battlefield<\/strong>. These are written, \u201cWhen [this object] enters the battlefield,\u2026\u201d or \u201cWhenever a [type] enters the battlefield,\u2026\u201d (<em>Murderous Redcap, Soul&#8217;s Attendant<\/em>).<\/p>\n<p>Each time an event puts one or more permanents onto the battlefield, all permanents on the battlefield (<strong>including the newcomers<\/strong>) are checked for any enters-the-battlefield triggers that match the event.<\/p>\n<p><u>Continuous effects that modify characteristics of a permanent do so the moment the permanent is on the battlefield<\/u> (and not before then). The permanent is never on the battlefield with its unmodified characteristics. However, continuous effects don\u2019t apply before the permanent is on the battlefield.<\/p>\n<p><strong><u>Leaves the Battlefield:<\/u><\/strong><\/p>\n<p><strong>Leaves-the-battlefield<\/strong> abilities trigger <strong>when a permanent moves from the battlefield to another zone<\/strong>, or when a phased-in permanent leaves the game because its owner leaves the game. These are written as, but aren\u2019t limited to, \u201cWhen [this object] leaves the battlefield,&#8230;\u201d or \u201cWhenever [something] is put into a graveyard from the battlefield,&#8230;\u201d (<em>Kalastria Highborn<\/em>).<\/p>\n<p>An ability that attempts to do something to the card that left the battlefield checks for it only in the first zone that it went to. An ability that <strong>triggers when a card is put into a certain zone \u201cfrom anywhere\u201d is never treated as a leaves-the-battlefield ability<\/strong>, even if an object is put into that zone from the battlefield (<em>Emrakul, the Aeons Torn<\/em>).<\/p>\n<p><strong><u>Trigger event verification:<\/u><\/strong><\/p>\n<p>Normally, objects that exist immediately after an event are checked to see if the event matched any trigger conditions. Continuous effects that exist at that time are used to determine what the trigger conditions are and what the objects involved in the event look like.<\/p>\n<p>However, some triggered abilities must be treated specially. They will trigger based on their existence, and the appearance of objects, prior to the event rather than afterward. The game has to \u201clook back in time\u201d to determine if these abilities trigger.<\/p>\n<ul>\n<li>Leaves-the-battlefield abilities (<em>Kalastria Highborn<\/em>).<\/li>\n<li>Abilities that trigger when a card leaves a graveyard (<em>Erebos&#8217;s Titan<\/em>).<\/li>\n<li>Abilities that trigger when a permanent phases out (<em>Ertai&#8217;s Familiar<\/em>).<\/li>\n<li>Abilities that trigger when an object that all players can see is put into a hand or library (<em>Stormfront Riders<\/em>).<\/li>\n<li>Abilities that trigger specifically when an object becomes unattached (<em>Grafted Wargear<\/em>).<\/li>\n<li>Abilities that trigger when a player loses control of an object (<em>Duplicity<\/em>).<\/li>\n<li>Abilities that trigger when a player planeswalks away from a plane.<\/li>\n<\/ul>\n<p><strong><u>Triggered abilities of Auras:<\/u><\/strong><\/p>\n<p>Some Auras have triggered abilities that trigger on the enchanted permanent leaving the battlefield. These triggered abilities can find the new object that permanent card became in the zone it moved to; they can also find the new object the Aura card became in its owner\u2019s graveyard after state-based actions have been checked.<\/p>\n<p>Examples: <em>Gift of Immortality<\/em> and <em>Fool&#8217;s Demise<\/em>.<\/p>\n<p><strong><u>Replacement effects that are not triggered abilities<\/u><\/strong><strong><u>:<\/u><\/strong><\/p>\n<p>Some permanents have text that reads \u201c[This permanent] enters the battlefield with&#8230;\u201d (<em>Chimeric Mass<\/em>), \u201cAs [this permanent] enters the battlefield&#8230;\u201d (<em>Meddling Mage<\/em>), \u201c[This permanent] enters the battlefield as&#8230;\u201d (<em>Clone<\/em>), or \u201c[This permanent] enters the battlefield tapped\u201d (<em>Boros Guildgate<\/em>). Such text is a static ability, not a triggered ability, whose effect occurs as part of the event that puts the permanent onto the battlefield.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline\"><strong>DELAYED TRIGGERED ABILITIES<\/strong><\/span><\/p>\n<p>An effect may create a delayed triggered ability that can do something at a later time. A delayed triggered ability <strong>will contain<\/strong> \u201c<strong>when<\/strong>\u201d, \u201c<strong>whenever<\/strong>\u201d, or \u201c<strong>at<\/strong>\u201d, although that word won\u2019t usually begin the ability<\/p>\n<p>Delayed triggered abilities come from spells or other abilities that create them on resolution, or are created as the result of a replacement effect being applied. That means a delayed triggered ability <strong>won\u2019t trigger until it has actually been created<\/strong>, even if its trigger event occurred just beforehand. Other events that happen earlier may make the trigger event impossible.<\/p>\n<p>Example: <em>Sneak Attack<\/em>, <em>Howl of the Horde.<\/em><\/p>\n<p>A delayed triggered ability will trigger only once, the next time its trigger event occurs, unless it has a stated duration, such as \u201cthis turn\u201d.<\/p>\n<p>A delayed triggered ability that refers to a particular object <strong>still affects it even if the object changes characteristics<\/strong>. However, if that object is no longer in the zone it\u2019s expected to be in at the time the delayed triggered ability resolves, the ability won\u2019t affect it.<\/p>\n<p><strong><u>Source of a Delayed Triggered Ability:<\/u><\/strong><\/p>\n<p>If a spell creates a delayed triggered ability, <strong>the source of that delayed triggered ability is that spell<\/strong>. The controller of that delayed triggered ability is the player who controlled that spell as it resolved.<\/p>\n<p>If an activated or triggered ability creates a delayed triggered ability, <strong>the source of that delayed triggered ability is the same as the source of that other ability<\/strong>. The controller of that delayed triggered ability is the player who controlled that other ability as it resolved.<\/p>\n<p>If a static ability generates a replacement effect which causes a delayed triggered ability to be created, <strong>the source of that delayed triggered ability is the object with that static ability<\/strong>. The controller of that delayed triggered ability is the same as the controller of that object at the time the replacement effect was applied.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline\"><strong>REFLEXIVE TRIGGERED ABILITIES<\/strong><\/span><\/p>\n<p>A resolving spell or ability may allow a player take an action and create a triggered ability that triggers \u201cWhen (a player) (does or doesn\u2019t)\u201d take that action. These <em>reflexive triggered abilities <\/em>follow the rules for delayed triggered abilities, except that they\u2019re checked immediately after being created and trigger based on wheter the trigger event occurred earlier during the resolution of the spell or ability that created them.<\/p>\n<p>Examples: <em>Heart-Piercer Manticore <\/em>and sacrifice a creature by its ability.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline\"><strong>ABILITITES TRIGGERED BY A GAME STATE<\/strong><\/span><\/p>\n<p>Some triggered abilities trigger when a game state (such as a player controlling no permanents of a particular card type) is true, rather than triggering when an event occurs.<\/p>\n<p>These abilities trigger as soon as the game state matches the condition. They\u2019ll go onto the stack at the next available opportunity. These are called <strong>state triggers<\/strong>. (Note that state triggers aren\u2019t the same as state-based actions.) A state-triggered ability doesn\u2019t trigger again until the ability has resolved, has been countered, or has otherwise left the stack. Then, if the object with the ability is still in the same zone and the game state still matches its trigger condition, the ability will trigger again.<\/p>\n<p>Some triggered abilities trigger specifically when a player loses the game. These abilities trigger when a player loses or leaves the game, regardless of the reason, unless that player leaves the game as the result of a draw.\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Last updated: 02 August 2017 Downloadable PDF file available\u00a0HERE DEFINITION Triggered abilities have a trigger condition and an effect.
