RE: "Prof. it!":The Ultimate Pokemon TCG Show! Episode 33: Charizard!
Wii Man, your reasoning does not make any sense. If the Luxchomp deck was PL-On, and the other decks were RR-On, wouldn't they make it RR-On so that Luxchomp deck wouldn't keep dominating?
Also, in my opinion, I reallllllllllyyyy think its going to be HGSS-On. All the cards in the sets are really balanced, so that wouldn't ruin creativity. You could run Donphan, Jumpluff, Steelix, Scizor, Kingdra, Machamp, Mew Toolbox, and a bunch of things from B&W. If it was PL-On, SPs would dominate again and that would lessen the amount of viable decks.
Nobody realizes how amazing this game would be if the rotation was HGSS-On...
