Flying

When Angel of Despair enters the battlefield, destroy target permanent.

Whenever a creature enters the battlefield under your control, you gain life equal to its toughness.

Lifelink, protection from white and from black

As long as you have 30 or more life and an opponent has 10 or less life, Blood Baron of Vizkopa gets +6/+6 and has flying.

At the beginning of each end step, if an opponent lost 2 or more life this turn, you may put a quest counter on Bloodchief Ascension. (Damage causes loss of life.)

Whenever a card is put into an opponent's graveyard from anywhere, if Bloodchief Ascension has three or more quest counters on it, you may have that player lose 2 life. If you do, you gain 2 life.

If you would gain life, you gain twice that much life instead.

Bestow {5}{W}{W} (If you cast this card for its bestow cost, it's an Aura spell with enchant creature. It becomes a creature again if it's not attached to a creature.)

Flying, first strike

Enchanted creature gets +4/+4 and has flying and first strike.

When Orzhov Pontiff enters the battlefield or the creature it haunts dies, choose one --

• Creatures you don't control get -1/-1 until end of turn.
