Sealock Monster⁣ - Theros⁣ (Uncommon)⁣ [62]

Sealock Monster is a 5/5 Octopus creature from the Theros set that requires its controller to have an Island for it to attack. With the ability to become monstrous for {5}{U}{U}, it gains three +1/+1 counters and can turn a target land into an Island, potentially disrupting your opponent's mana base while boosting your own. This card fits well in control decks that utilise blue's land manipulation and can be a solid threat in the late game. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
