Mewtwo-EX (xy8-157 Holofoil) is a Basic Pokémon-EX from the BREAKthrough set and is printed as a Rare Ultra. It has Photon Wave, which reduces damage from the Defending Pokémon by 30 during your opponent's next turn and a heavy Psyburn attack that deals 120 damage. Its EX status means it yields two Prize cards when knocked out, shaping its role as a high-risk, high-reward attacker.
