Mouth of the Hermit

Aegis - Aegis protects a unit or player from one enemy spell or effect. It doesn't block friendly effects, nor does it stop battle damage from Killer attacks, Relic Weapons, or normal attacking and blocking.

Voidbound - Cards with Voidbound cannot leave the void.

Devour - When played, you may destroy that many cards from the top of the enemy void to get the listed effect.
