A: It will have Hexproof from White! It won’t have “general” Hexproof unless it exiles something with “general” Hexproof.

A: This player’s opponent will face the tremendous power of Brisela, Voice of Nightmares! When this player exiles both Hanweir Garrison and Hanweir Battlements, the game checks if they make a melded pair. Since they are no longer on the battlefield, they become Bruna and Gisela again, two cards that make a melded pair, so they return to the battlefield melded as Brisela!

A: This is treated as a GPE – Hidden Card Error. “It is HCE when a player creates a set, with the intention of creating a set, but the set ends up with too many cards in it. Notice that there is no need to draw cards, the infraction is not called Drawing Extra Cards for a very good reason. Tezzeret, Artifice Master’s second ability reads: Draw a card. If you control three or more artifacts, draw two cards instead. The player was instructed to make a set of 1 card, then add that set to their hand. Instead, they put 2 cards in the set they wanted to add to the hand. So, this is HCE, we reveal the 2 cards from this set, opponent chooses 1 to draw and 1 to be shuffled away.”

A. If Xantcha, Sleeper Agent is entering the battlefield, the player who’s putting it onto the battlefield must choose to give control of it to one of their opponents using its control-changing effect. When that opponent leaves the game, the control-change effect giving them control of Xantcha ends. When that happens, Xantcha returns to the control of its previous controller: the player who was making the choice of who to give it away to. That’s usually going to be Xantcha’s owner.

A: “AP’s Fated Infatuation token is and will always be a Carnage Tyrant…barring intervention from the players, of course. (AP could, after all, cast another Rush and turn it into something else temporarily, or Nick could cast Mirrorweave, or they could do any of a million other things to change it.)

When you copy something that’s been turned into a copy of something else, you’re not separately copying both the original card and the effect that’s turning it into a copy of something else. What you’re copying is only the copiable values of that card. Those values happen to have already been modified by the other copy effect, so the values you receive are the modified ones.

Once Polymorphous Rush’s effect wears off during the cleanup step, there’s no longer anything saying that the Grizzly Bears is a Tyrant, so it’s not one anymore, but the Fated Infatuation token is still a Tyrant, because those are the values it copied–the fact that it’d look different if you copied the same permanent with something else now doesn’t matter.

This is explicitly laid out in the rules for copying objects:

706.2b Once an object has been copied, changing the copiable values of the original object won’t cause the copy to change”
