I've tried to try out a deck like this for a while now and its just not perfect yet.
Pokemon(17)
{W} Keldeo EX x3
{P} Mewtwo EX x2
{W} Blatoise x4-2-3
{L} Emolga(DE) x3
Trainers/Supporters/Stadiums/Tools(30)
Pokemon Catcher x3
Eviolite x4
Ultra Ball x3
Great Ball x2
N x4
Professor Juniper x3
Pokemon Communication x3
Cheren x2
Cilan x1
Heavy Ball x2
Level Ball x3
Energy(13)
{C}{C} x3
{W} x10
Strategy:You wil want to try and set up a Blastoise as quick as you can and use Emolga to get out Mewtwo EXs and Keldeo EXs early in the game so you can use Blastoise to power the up with energies.
