Set: Promo Pack: Throne of Eldraine Type: Creature — Specter Rarity: RareFlying
Whenever Thief of Sanity deals combat damage to a player, look at the top three cards of that player's library, exile one of them face down, then put the rest into their graveyard. For as long as that card remains exiled, you may look at it, you may cast it, and you may spend mana as though it were mana of any type to cast that spell.
