DNA,
Yeah, you basically have to fight fire with fire (Well, EX VS EX) and that's kind of a problem considering that you're basically giving each other 2 Prizes.
Last night I had to play against Judge Michael and almost won. I basically was always drawing Regigigas on my first draw because of the texture and not using sleeves. I beat his Zekrom EX with it!
Planning on putting Zekrom EX into my Eelzone deck.
