Aclazotz, Lord of Night

Lifelink, Flying
Whenever Aclazotz deals combat damage to a player, exile the top card of your library. At the beginning of your upkeep, you may cast a card exiled with Aclazotz if it's converted mana cost is equal to or less than your devotion to black.
You may pay {3}{b}{b} and sacrifice a creature while Aclazotz is on your graveyard. If you do, return it to the battlefield. You can only activate this ability if you control a card named Temple of Aclazotz.
