M Diancie-EX (xyp-XY44-Holofoil) is a Fairy-type MEGA Pokémon-EX promo from the XY Black Star Promos line. Its Diamond Force attack deals 100 damage and creates a one-turn effect that prevents damage dealt to your Pokémon by opponent's Pokémon-EX while this card remains your Active Pokémon. As a Mega Pokémon-EX, evolving into it ends your turn and your opponent takes two Prize cards if it is Knocked Out.
