Green Mana Battery - Fourth Edition (Rare)

Green Mana Battery is a four-mana artifact from Fourth Edition that allows you to accumulate charge counters for later use. By spending two mana and tapping it, you can add green mana based on how many counters you choose to remove, effectively ramping your mana for larger spells. This card works well in decks focused on generating additional mana or utilising spells with high mana costs, though it requires a bit of setup to maximise its potential. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
