The trouble with those Pokemon + 59 Energy decks is that no-one will fall for it (in Masters anyway).
As soon as they see 2 mulligan hands with nothing but Energy, the opponent will stop drawing their optional extra card and wait as the poor guy keeps failing to get a Basic. Eventually, a judge will be called over and then the guy will die of embarrassment and lose next turn.
Seeing as he said he wanted to PLAY at States, you should give him a deck that he can . . . y'know . . . PLAY.
thanks guys thats a great help i might just play that purugly g one
Don't play that. You don't want your Step Dad to go through all those rounds, with one gimmick that will never work - he'll just get so bored and it'll put him off other tournaments. Go with Baby Mario's suggestions
All depends on how much notice it is before the tournement.
And how much he's played.
He's going to lose every game with Purgly, so its not a superior option to anything. I'm sure he can be taught the basics today/tomorrow - States is a bad starting tournament if you're that new.
Shuppet or Gyarados would be my suggestions.
