All of you people who think that cards like poliwhirl and eevee can stop
mewtwo are idiots.  Mewtwo's card says that if you discard one psychic
energy you can prevent ALL effects of attacks.  That means that tail wag and
amnesia will not work.  Also, no smart player would ever put another mewtwo
on their bench.  Plus there is a solution to the problem of the non
mulliganing opponent. It is called maintenance. I maintain that the only way
to beat a mewtwo deck is energy removal, and then kill off the mewtwo with a
powerful pokemon.  You would not be able to have five energy on mewtwo,
because you have to discard one energyevery time you use barrier.  The only
way to combat this would be if none of your opponents pokemon, on the bench
or in play, had enough energy to attack mewtwo next turn, letting you use
psychic instead of barrier.
Thanx,
