This limitation makes it a strategic choice in blue control decks, as it can deter opponents from attacking if they lack Islands. However, if you don't control any Islands, you'll have to sacrifice it, so careful management of your mana base is essential. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.\n\u003c!-- AI-SEO END --\u003e","brand":"Vault of Cards | Magic: The Gathering Singles | UK MTG Shop","offers":[{"title":"English \/ Excellent \/ Normal","offer_id":43779924459655,"sku":"4ED-133719","price":0.11,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/6900\/4423\/files\/e474391c-9ff0-4db4-9352-3fc07eeb4b51.jpg?v=1776252199","url":"https:\/\/vaultofcards.co.uk\/products\/sea-serpent-fourth-edition-common-5932","provider":"Vault of Cards","version":"1.0","type":"link"}
