Boros Keyrune⁣ - Gatecrash⁣ (Uncommon)⁣ [227]

Boros Keyrune is a three-mana artifact from Gatecrash that can tap for either red or white mana, making it versatile in colour-fixing. For an additional cost, it can turn into a 1/1 Soldier creature with double strike, allowing it to deal damage both in the first-strike and regular damage steps. This functionality makes it valuable in aggressive Boros strategies, providing both mana and a creature threat, though it can be vulnerable to removal. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
