Thanks. He is pretty much a rookie at this point so probably did not have much. He is trying to build a strong grass type deck. Basically like I said, if anyone can give me a few names, I'm really appreciated.
Shaymin EX and Celebi EX are the only two EX Pokemon currently released, so not much choice for EX Pokemon there, but those two are really only good as support Pokemon, and shouldn't be his main attackers for his deck. Shaymin is really good if you're behind in a match or near the end of one, though.
Other ones that might help his deck are Mewtwo EX, which, at least in competitive play, is a staple in almost every deck because of its X-Ball attack. Mewtwo EX actually came in a tin that had booster packs inside (this tin retailed for $15), so you could get him Mewtwo EX and a few boosters this way.
