My brain hurts. If both me and my opponent has a Mimic Vat in play, and I have a Nim Deathmantle as well, what happens? I know there's some APNAP stuff in here, but in what instances am I screwed by his Mimic Vat or not? Mimic Vat Whenever a nontoken creature is put into a graveyard from the battlefield, you may exile that card. If you do, return each other card exiled with Mimic Vat to its owner's graveyard. (3), tap: Put a token onto the battlefield that's a copy of the exiled card. It gains haste. Exile it at the beginning of the next end step. Nim Deathmantle Whenever a nontoken creature is put into your graveyard from the battlefield, you may pay (4). If you do, return that card to the battlefield and attach Nim Deathmantle to it.
