The absolute best person to use against mr. mime is Bulbasaur. lets play this
out. Your opponent wins the coin toss, so he plays mr. mime and attaches an
energy. Bulbasaur attaches an energy. Mr. Mime attaches another energy and
does 10 damage to you. Bulbasaur attaches another energy and does leech seed.
that not only does 20 damage to mime, but it takes off that damage counter.
repeat the process again until mr. mime is dead.
