Zakhiz, herald of possession

Deathtouch, Haste, Trample
Auras you control have ward-sacrifice a creature.
When you cast Zakhiz choose an opponent that
has not been chosen yet, search your library for
a curse aura enhancement with mana value 6 or
less and put it into the battlefield attached to that player then repeat this process until each of your opponents have been chosen.
Im one to welcome catastrophe. But that thing, I fear
its far worse. ~ Gerrard, Drifter of the plains
