Trust me, Smogon's the best. Last time I was on PokeBattleCenter, the chat was clogged up with spam. That doesn't happen on Smogon, and if it does, the Mods take care of it.
See, I used to do that, but now I just stick to one team, modifying it as I see fit. Works really well.
I never do Ubers, anyone can do it. It's just sticking legends in to battle...And I hate using legends, except for standard OU ones (Three birds, three dogs, three Regi's, the three lake pokemon, and BW's three, Terrakion, Virizion, and Cobalion).
