Create X 2/2 black Zombie creature tokens with decayed, where X is half the number of creature cards in your graveyard, rounded up. (A creature with decayed can't block. When it attacks, sacrifice it at end of combat.)\nFlashback {3}{B}{G} (You may cast this card from your graveyard for its flashback cost. Then exile it.)
