Mimic Vat

Imprint - 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},{t}: 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.
