FlyingWhenever Hellcarver Demon deals combat damage to a player, sacrifice all other permanents you control and discard your hand. Exile the top six cards of your library. You may cast any number of spells from among cards exiled this way without paying their mana costs.
Annihilator 2 (Whenever this creature attacks, defending player sacrifices two permanents of their choice.)Whenever an opponent sacrifices a nontoken permanent, put that card onto the battlefield under your control.
As an additional cost to cast this spell, sacrifice a creature.You draw cards equal to the sacrificed creature's power, then you gain life equal to its toughness.
Counter target spell or ability that targets a permanent you control.This spell costs less to cast if it targets a spell or ability that targets a creature you control with power 7 or greater.
Search your library for up to four land cards with different names and reveal them. An opponent chooses two of those cards. Put the chosen cards into your graveyard and the rest into your hand. Then shuffle.
Auras attached to permanents you control have umbra armor. (If an enchanted permanent you control would be destroyed, instead remove all damage from it and destroy an Aura attached to it.)
