Containment Membrane⁣ - Mystery Booster⁣ (Common)⁣ [52]

Containment Membrane is a two-mana Aura from The List that enchants a creature, preventing it from untapping during its controller's untap step. With its Surge ability, you can cast it for just one blue mana if another spell has been played this turn, making it a flexible option for disrupting opponents. This card works well in control decks that aim to stifle key threats and maintain board advantage. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
