Here's a list of the decks people think will be used:
Kingdra
Scizor
Tyranitar
Dusknoir
Gengar
Gliscor
Magmortar+Heatran
Torterra
Machamp
Froslass
Mario
Electivire+Magnezone
Raichu
AMU
Metagame will be flooded with Machamps, Dusknoirs and Raichus. You guys are making this list way too wide of a spectrum. Sure, they will be played, but in moderation.
my meta-game: (the non-noobish stuff)
1 T-Tar
2 gengar's
2 gengar/dusknoir
1 magmorter
4-5 ???'s (the other good people haven't been at league that much so i don't know what their playing...)
Probably Dusknoir/Gengar and Kingdra more than anything. We may see some Torterra's and Heatran/Any Fire Type. Palkia/Roserade is a deck that is hyped to be a winner, too. Then there are the rogue decks. Pretty much every legal card right now can be made into a decent deck if played right. I know a guy who made a deck with Butterfree/Cherrim and got 2nd in a BR.
