Iasir, Priest of Desolation

Creature spells you own have reverent (You may
exile a non-Human creature card from your
graveyard as you cast them.)
When a reverent creature with power 3 or less
enters the battlefield under your control, you
may sacrifice it. If you do, draw two cards.
Whenever Iasir dies or is exiled from your
graveyard, exile target nonland permanent.
