I don't play competitively so I just use pokemon as I find them and if they work out, I keep them on.
Here's my White 2 team:
Samurott, (Torrent) Aqua Jet/Swords Dance/Waterfall/Megahorn
Braviary, (Defiant) Return/Superpower/Roost/Brave Bird
Chandelure, (Flame Body) Shadow Ball/Flamethrower/Will-O-Wisp/Energy Ball
Lucario, (Inner Focus) Dark Pulse/Aura Sphere/Close Combat/
Electivire, (Motor Drive) Volt Switch/Thunderbolt/Earthquake/Ice Punch
Altaria, (Natural Cure) Toxic/Roost/Earthquake/Draco Meteor
Recently, after beating the Elite 4, I've switched out Braviary and Altaria for:
Ludicolo (Rain Dish) Scald/Ice Beam/Giga Drain/Synthesis
Honchkrow (Moxie) Sucker Punch/Brave Bird/Superpower/Roost
Also, Chandelure and Samurott take turns with:
Volcarona (Flame Body) Roost/Overheat/Bug Buzz/Quiver Dance
Though to be honest, I'm not as happy with Volvarona as I thought I'd be. I want a Drought Ninetails, but Dream World isn't cooperating with a female vulpix...
