Quote from iSergiant »This instead of snappy..?
Creature - Zombie Wizard
Whenever Dreadhorde Arcanist attacks, you may cast target instant or sorcery card with converted mana cost less than or equal to Dreadhorde Arcanist's power from your graveyard without paying its mana cost. If that card would be put into your graveyard this turn, exile it instead.
Not without any way to pump its power. It might be playable in Modern, but it needs suspend cards.
