# Aether Membrane Aether Membrane is a modest uncommon from Duel Decks: Venser vs. Koth that appeals primarily to players building around blue-based control or artifact synergy strategies. The card's effect of dealing damage whenever creatures attack offers defensive utility in limited formats, though it sees minimal constructed play. Collectors value this card mainly for set completion rather than inherent desirability. As a nonfoil uncommon from a supplemental product, it remains affordable and readily available. The Duel Decks series itself attracts casual players and budget-conscious collectors, making Aether Membrane a common pickup for those assembling the full set rather than a sought-after piece.
