M Mewtwo-EX (xy8-63) is a Mega Evolution Pokémon-EX from the BREAKthrough set and a Rare Holo EX printing. Its attack Vanishing Strike deals 150 base damage and gains +50 damage and ignores Resistance and effects on the opponent's Active Pokémon if any Stadium is in play. As a Mega Evolution it follows the Mega Evolution rule that ends your turn when it evolves and causes the opponent to take two Prize cards if knocked out as a Pokémon-EX.
