Yhorm, Giant of Cinder

When Yhorm enters the battlefield, sacrifice it unless
it Re-Awakened.
Whenever Yhorm enters the battlefield or attacks,
each opponent discards a card, then each opponent
who didn't discard a nonland card this way loses
3 life.
Re-Awakened - {b}{b}{r}{r}, Exile five other cards
from your graveyard. (You may cast this card from
your graveyard for its Re-Awakened cost.)

[Kroxa, Titan of Death's Hunger]
