A: “NAP is not entitled to know how many cards AP chose from one zone or the other. They may be able to determine that information on their own by looking at the very large number of cards that are now face-up in exile and figuring out if something that they know was in a specific zone is missing, or by watching the physical actions AP was performing during the search, but AP has no obligation to tell them, nor to assist in figuring it out.”

A: Tarmogoyf will be a 0/1 and survive!

“Tarmogoyf has a characteristic-defining ability that defines its power and toughness. (“Tarmogoyf’s power is equal to the number of card types among cards in all graveyards and its toughness is equal to that number plus 1.”) It also has a printed power and toughness. (* /1+*)

Normally, Tarmogoyf’s CDA overrides its printed power and toughness. However, if Merfolk Trickster has removed that ability, we are left to determine Tarmogoyf’s power and toughness the same way we determine those values for any other creature: by looking at what’s printed in its power/toughness box.  For Tarmogoyf, what’s printed there is “* / 1+*”. Since * does not have a numerical value, we use 0 instead, just as we do for any other number that can’t be determined. Therefore, Tarmogoyf’s power and toughness is “0 / 1+0”, also known as 0/1.

So why is Tarmogoyf a 0/1 under the effects of a Merfolk Trickster? For the same reason a Dauntless Bodyguard would be a 2/1, or a Pardic Wanderer would be a 5/5: that’s what’s printed on the card.”

A: “The ability of a Winding Constrictor entering the battlefield in this situation will not apply to the Constrictor itself, and therefore Winding Constrictor should only receive one counter.

614.12 is explicitly defining the set of replacement effects that modify how a permanent enters the battlefield, and it does so by listing two basic classes of such replacements: replacements from that permanent that affect only that permanent, and replacements from sources other than that permanent.

The rest of 614.12 is then a bunch of further detail about how to determine which replacements from within these basic classes should be applied, but none of that detail matters here, because we already know enough to know that Winding Constrictor’s ability should not be applied, because it does not fall into either of these basic classes.”

A: The answer to this question is covered by rule 112.6k: “an ability whose cost or effect specifies that it moves the object it’s on out of a particular zone functions only in that zone, unless that ability’s trigger condition, or a previous part of that ability’s cost or effect, specifies that the object is put into that zone. The same is true if the effect of that ability creates a delayed triggered ability whose effect moves the object out of a particular zone.

Example: Reassembling Skeleton says “{1}{B}: Return Reassembling Skeleton from your graveyard to the battlefield tapped.” A player may activate this ability only if Reassembling Skeleton is in their graveyard.”

So, a player can only activate Multani’s ability whenever she’s on that player’s graveyard.
