This is Mew EX, And it's weakness is psychic and the damage is X2, so if I took a Mew two EX: http://www.bing.com/images/search?q=Mewtwo Ex Pokemon Card&Form=IQFRDR#view=detail&id=9C995F6FC688D729EB1277CE78BF789209F15B2E&selectedIndex=2
All Mewtwo EX's attacks would do double damage, because it is a psychic type.
