True Polymorph [Dungeons & Dragons: Adventures in the Forgotten Realms]

Set: Dungeons & Dragons: Adventures in the Forgotten Realms Type: Instant Rarity: Rare Cost: {4}{U}{U} 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.)Flashback {3}{B}{G} (You may cast this card from your graveyard for its flashback cost. Then exile it.) Maybe a little *too* convincing.
