the palkia & palkia x are a decent techs. i like the mewtwo & mewtwo x as it often comes up (with the pixies having free retreat) to do some decent hurt in a turn (energy absorbtion its first turn, to get mesprit x's discarded two psychic energies). this deck is working pretty well for me.
i do not like call energy, as it bypasses the benefits of playing the LA pixies from the hand. i put in two multi energy, as palkia cannot attack without it, and there have been a lot of times that it could fetch me a snowpoint stadium that i desperately need. also, when using palkia x's power (you had better have a switch, but sometimes you do not), the opponenet will always pick palkia (if the power is used from the bench).
quickballs work well for me in this deck. i have switches in the deck, also.
just my two cents.
