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 attack and blocking.
Market - Merchants allow you to store up to five cards in your Market when you build a deck. When cards are retrieved from a Market, they are drawn.
