Secret Weapon

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.

Shift - When played, you may instead pay the Shift cost. Shifted units can't attack, block, or be selected until they emerge.

Emerge - After three turns, Shifted units emerge and get Unblockable that turn.
