Card for card, there a lot of Pokemon better than Mewtwo, my favorite example is Cobalion, Mewtwo needs seven energies to OHKO Cobalion, and If it can't do that 140 in three turns (that's only if Cobalion doesn't have any energy at the start of the three turns.), you have to switch Mewtwo, because he's going to get IB'd and yeah, it'll take two or three turns to kill Mewtwo, but you'll be up two prizes, and they lose the energies they used to attack Cobalion.a fully built Cobalion, special metals and eviolite can take two hits from psycho drive and still live. Donphan makes Mewtwo a glorified xatu, you only need one energy to hit for 70 and his poke-body redueses that twenty from the x ball, meaning you have to add at least 7 energy to OHKO Donphan. Mewtwo is overrated, and you will all soon realize it.
