Trample, rampage 12, menace

This creature can be cast by Cycle of the World. While this sorcery summoned creature is on the battlefield, your other sorcery summoned creatures are indestructible during every player's combat phase. If all creatures sacrificed for this creature were sorcery summoned, you don't have to pay mana to activate its effects. Once per turn, you can pay {8}; destroy all non-land permanents your opponent controls, and, if you do, deal six damage for each card destroyed this way. All other black creatures you control have deathtouch and annihilator 4.
