Splitting the Powerstone [The Brothers' War]

Set: The Brothers' War Type: Sorcery Rarity: Uncommon Cost: {2}{U} As an additional cost to cast this spell, sacrifice an artifact.Create two tapped Powerstone tokens. If the sacrificed artifact was legendary, draw a card. (The tokens are artifacts with “{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.”) As the glowing stone broke apart, so too did the last shred of the brothers' bond.
