Sealock Monster⁣ - Mystery Booster⁣ (Uncommon)⁣ [42]

Sealock Monster is a 5/5 Octopus creature from The List that requires the defending player to control an Island in order to attack. It can become monstrous for {5}{U}{U}, adding three +1/+1 counters and turning a target land into an Island, which can disrupt your opponent's mana base. This card fits well in control strategies that can manipulate the board state while also providing a substantial threat. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
