Doubles can be pretty gay though. Cherub will be perfect on any team!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Joking aside (even though the Cherub thing is kinda true, but Groudon is banned), Strong EQers and a teammate that resists might be the format of most teams. That in mind, you'll see a lot of flyers and levitaters, levitaters being the dominant choice. Hmm, this will be interesting to see who will win.
The last Pokemon tournament was won by a fat 13 year old kid who somehow was able to use a freaking Groudon -_-
IIRC his team was Garchomp, Hippowdon, Groudon, and some steel type...I think. Don't ask me how he got Groudon in.
