Misthelm

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.

Entomb - The ability of a unit with Entomb will activate when it dies. This combines well with effects that sacrifice units as a cost.

Flying - Flying units can only be blocked by other flying units, but can block ground units normally. They can also be directly attacked by Killer units and Relic Weapons.

Reckless - Units with Reckless must attack.

Summon - Does something when played
