Gruul Keyrune⁣ - Gatecrash⁣ (Uncommon)⁣ [230]

Gruul Keyrune is a three-mana artifact from Gatecrash that taps for either red or green mana. For an additional cost, it can become a 3/2 Beast creature with trample until the end of your turn, providing both mana acceleration and a temporary creature to pressure opponents. This versatility fits well in Gruul strategies that benefit from mana ramp and aggressive board presence. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
