CMT (CharMasterTrainer) , don't listen to what BanginBox says. He's prolly just mad because he lost his CC.
Actually, it ain't my place to say so, so forget I ever said that. Um...yeah. Anyway, BanginBox means, if I could rephrase this:
CharizardMasterTrainer: Gardevior takes a lot of skill to handle because of its power, and can cause problems if not used correctly. The 20 damage rule can be harsh, so next time a huge event is coming up, practice loads before the tournament so you have experience with the deck. If Gardevoir continues not to work for you, consider something else for the PreReleases.
BanginBox, lay off on the insults. It makes you look like a real noobie, even though you may not be.
