For future reference, post your team with their items, natures, EVs, moves, and abilities.
As for your team, here's some stuff:
1) Scolipede w/Black Sludge
Nature: Jolly
EVs: 252 HP, 34 HP, 224 Speed
Moves: Megahorn, Baton Pass, Swords Dance, Protect/Poison Jab/Earthquake
Ability: Speed Boost
Since Game Freak decided to grace Scolipede with Speed Boost and an extra 10 base Attack, it now has use as a good Baton Passer. The idea is to send out Scolipede, use Swords Dance, then Baton Pass those boosts to a teammate, giving them +2 to Attack and +1 to Speed, which every physical attacker loves. The EV spread is to ensure its survival so it can pass the boosts.
2)Noivern w/Choice Specs:
Nature: Timid/Modest
EVs: 252 Special Attack, 252 Speed, 4 Sp.Defense
Moves: Draco Meteor, Dark Pulse, Flamethrower/Boomburst, Hurricane
Ability: Infiltraitor
Noivern is the living definition of "hit hard and fast". It has high speed, and with Choice Specs equipped, its average Sp.Attack is boosted to powerful levels.
3)Scrafty w/Leftovers
Nature: Adamant
EVs: 252 HP, 252 Sp.Defense, 4 Attack
Moves: Bulk Up, Drain Punch/High Jump Kick, Payback/Poison Jab, Rest
Ability: Shed skin
The idea here is to power up it with Bulk Ups, then whack stuff with its attacks. Rest and Shed Skin make a semi-reliable form of recovery, helped by Leftovers. Poison jab can be used to hit Fairies if need be.
4) (Mega) Pinsir w/Pinsirite
Nature: Jolly
EVs: 252 Attack, 252 Speed, 4 Defense
Moves: Close Combat, Swords Dance, Quick Attack/Stone Edge/X-Scissor, Return
Ability: Aerilate
Pinsir isn't worth using unless you use its mega form, and this is apparently what Smogon reccomends.
And I have no idea what people do with Banette or Clawizter. Hopefully someone else will come along and add to the conversation...
