#1 Mewtwo V Alternate Art This is my favorite Mewtwo card from this set
Mega Froslass is not good simply because of the instant damage itself, but because it forces you to limit your hand throughout the entire game, as any Snorunt on the bench could evolve and oneshot you with one energy attachment, and this way it limits counterplay to other attackers that synergise with the Snorunt line
Then, Mewtwo has a fantastic VSTAR move that deals 120 damage to any other V Pokmon your opponent controls, and this can be a game finisher attack
