Isaac

When Isaac enters, mill five cards, then return
an Aura or Equipment card from your graveyard to your hand.
Whenever a creature you control that's enchanted
or equipped attacks, create a Junk token. (It's an artifact with "{t}, Sacrifice this token: Exile the top card of your library. You may play that card this
turn. Activate only as a sorcery.")
