Kaileoc, Deserted Annihilator

Haste, trample
When Kaileoc, Deserted Annihilator enters the
battlefield, destroy all other creatures. Then for
each creature destroyed this way, search your
library for a creature card and put it on the battlefield under your control.
At the beginning of your upkeep, as long as
Kaileoc, Deserted Annihilator is in play, you sacrifice a creature.
