So I've been getting back into Black 2 while I wait for SM to come out and I'm looking for a good team to beat the Champion's Tournament at the PWT.

So far I've been using:
Salamence @ Life Orb
Ability: Moxie
EVs: 64 Atk / 192 SpA / 252 Spe
Naive Nature
- Draco Meteor
- Outrage
- Fire Blast
- Earthquake

Scizor @ Leftovers
Ability: Technician
EVs: 252 HP / 40 Atk / 216 SpD
Adamant Nature
- Swords Dance
- Roost
- Bullet Punch
- Bug Bite

Starmie @ Choice Specs
Ability: Analytic
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Hydro Pump
- Thunderbolt
- Psychic
- Ice Beam

This was able to carry through the Gym leader tournaments with ease, but I've had much less success in the Champion tournament. Does anybody have any ideas?
