Chandelure (M) @ Air Balloon

Role: Left Side, Sweeper, T-room set up / Support
Trait: Flash Fire
EVs: 64 HP / 192 Def / 252 SAtk
Relaxed Nature (+Def, -Spd)
- Trick Room
- Heat Wave
- Shadow Ball
- Energy Ball
Heat wave lets him hit 2 of my opponents at once, while not touching his allies, making for a great attack here. Trick Room enables this entirely slow team to start hitting first agaisnt most opponents. Shadow Ball is STAB that singles out one specific opponent, and Energy Ball is coverage. Air Balloon protects from the crazy butt earthquake weakness, meaning someone will have to most likely go for a neutral hit to take him down to the ground. Defense Ev's and nature to give extra support to make him bulky with Light Screen from Forretress.
Forretress (M) @ Normal Gem

Role: Middle, Support
Trait: Sturdy
EVs: 96 HP / 160 Atk / 252 SDef
Brave Nature (+Atk, -Spd)
- Explosion
- Rest / Rock Slide
- Sleep Talk / Heavy Slam
- Light Screen
Light Screen supports the whole team's bulk, which is amazing, Although he still requires pretty much maxed out Sp Def Ev's to contain a bulky disposition in that stat. Explosion won't affect my team mates ( :D ) because they're both ghost types, while having a normal gem will jack up it's power really really high, I can't decide on his other two moves, as Rest Talk can be annoying and keep my opponent at bay while they're struggling to kill him, but Rock Slide and Heavy Slam enables him to do some T-room sweeping, and I'm particularly fond of the second choice.
Jellicent (F) @ Sitrus Berry

Role: Right Side, Sweeper and Annoyer
Trait: Water Absorb
EVs: 60 HP / 252 Def / 196 SAtk
Relaxed Nature (+Def, -Spd)
- Water Spout
- Recover
- Confuse Ray
- Ice Beam
Can sweep with Water Spout fairly well, and it hits in the same radius, only from the right as Heat Wave does. Recover can keep Waterspout going if you have 2 other team mates pounding down your opponents doors, Confuse Ray can do some twisted up stalling, so that you can use Recover and start Spouting again. Ice beam gives coverage for dragons, which Heat Wave and Water Spout both normally don't agree with.
