By spending two mana and tapping it, you can place a charge counter on it, and later, you can remove those counters to add blue mana, effectively doubling your mana output based on how many counters you’ve stored. This card is useful in control decks that need to ramp up their mana for big spells or complex combos. 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":43756214386823,"sku":"4ED-98788","price":0.26,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/6900\/4423\/files\/cd2cb84e-c079-486e-87ad-d188fe38bc76.jpg?v=1776178614","url":"https:\/\/vaultofcards.co.uk\/products\/blue-mana-battery-fourth-edition-rare-6152","provider":"Vault of Cards","version":"1.0","type":"link"}
