Magic Mirror

Imprint - Whenever a non-token enchantment
goes to the graveyard from play, you may exile
that card. If you do, return each other card exiled
with Magic Mirror to its owner's graveyard.
{3}, {t}: Create a token that's a copy of a card
exiled with Magic Mirror. You may attach any
permanent you legally can to it. Exile that token
at the beginning of the next opponent's end step.
