Edea, Hallowed One

Once per turn, you may cast a nonland card from
your graveyard by discarding cards from your
hand equal to that card's total converted mana
cost. If a noncreature card cast this way would be
put into the graveyard, exile it instead.
At the beginning of the next end step, if you have
no cards in hand, sacrifice Edea, Hollowed One.
No one escapes life alive.
