Aegis Cards can't leave the enemy player's Market or void.
Card sounds may differ from in-game as they get updated.
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.
Market - You can store up to five unique cards in your market that are not in your main deck when you build your deck. Your market is hidden from the enemy player.
