Ninetails @ Focus Sash
Timid Nature
Ability: Drought
EVs: 4hp/252Satk/252spd
-Hypnosis
-Nasty Plot
-Fire Blast
-Solarbeam
Ninetails's main purpose is to set up sunlight via Drought. However, it can also sweep thanks to two set up moves in Hypnosis and Nasty Plot. Fire Blast and Solarbeam provide good coverage.

Salamence @ Dragon Fang
Naive
Ability: Intimidate
EVs: 252atk/4Satk/252spd
-Dragon Dance
-Outrage
-Earthquake
-Fire Blast
The classic DD Mence is up to its old tricks. If it can, it'll set up Dragon Dance, and proceed to wreck stuff. Earthquake has amazing neutral coverage when combined with Outrage. Fire Blast covers what Earthquake doesn't

Venusaur @ Leftovers
Jolly
Ability: Chlorophyll
EVs: 4hp/252atk/252spd
-Solarbeam
-Sleep Powder
-Growth
-Hidden Power [fire]
With its double speed and sleep powder, Venasaur has the potential to set up (via growth) and sweep. Earthquake provides good coverage when combined with Seed Bomb, and means steels won't wall it. Stuff like Skarmory and Ferrothorn may prove problematic.

Arcanine @ Leftovers
Adament
Ability: Intimidate
EVs: 100hp/152atk/252spd
-Morning Sun
-Flare Blitz
-Wild Charge
-Close Combat
Despite the constant recoil from Flare Blitz, its 100 hp evs, Leftovers, and Morning sun (boosted by the sunlight) help keep it alive. Wild Charge is for waters.

Heatran @ Air Balloon
Naive
Ability: Flash Fire
EVs: 4atk/252Satk/252spd
-Flame Charge
-Fire Blast
-Earth Power
-Dragon Pulse
Heatran speeds up with Flame Charge, and then sweeps. With flash fire, not only is it immune to fire moves, but they make its already powerful fire blast even stronger. The Air Balloon keeps it safe from ground moves.

Gengar @ Leftovers
Timid
Ability: Levitate
EVs: 4hp/252Satk/252spd
-Substitute
-Disable
-Shadow Ball
-Thunderbolt
Uses substitute and disable to attempt to rid of the foe's best move against it, and sweeps with Thunderbolt and Shadow Ball. Ferrothorn can cause issues, as can Excadrill, but there are plenty of Pokemon on my team that can deal with those.
Threat list:
-Weather changers are obviously an issue.
-A baton pass team pwned me.
-I suppose Scarftran could be an issue.
Any help is appreciated.
