When Entomber Exarch enters, choose one —

• Return target creature card from your graveyard to your hand.

• Target opponent reveals their hand. You choose a noncreature card from it. That player discards that card.

Deathtouch (Any amount of damage this deals to a creature is enough to destroy it.)

When this creature enters, search your library for a card, put that card into your graveyard, then shuffle.
