Soulcipher Board // Cipherbound Spirit: Innistrad: Crimson Vow

Soulcipher Board enters the battlefield with three omen counters on it. {1}{U}, {T}: Look at the top two cards of your library. Put one of them into your graveyard. Whenever a creature card is put into your graveyard from anywhere, remove an omen counter from Soulcipher Board. Then if it has no omen counters on it, transform it.
