Natural Cure

Leaf Storm
Stealth Rock
U-Turn
Earth Power
Celebi, is a decent lead in my opinion. Sets up rocks, OHKO's opposing Swamperts and Hippowdon with a STAB Leaf Storm. U-Turn against anything that I feel necessary, and keep Celebi alive incase of Vaporeon, as Vaporeon screws Suicune. Earth Power is useful against Metagross.

Wyche @ Leftovers

Pressure
Bold
Calm Mind
Surf
Rest
Sleep Talk
My favorite wall in the current OU meta. Surf, being the only attack on it for this set, becomes amazingly powerful after a few Calm Minds, capable of taking down entire teams with it. Rest/Sleep Talk go together in order to prevent Suicune from being KO'd, and helps set up Calm Mind. The only thing that wrecks this guy is Vaporeon with it's Water Absorb.

Mahon @ Leftovers
252 HP/112 Atk/144 Def
Sturdy
Relaxed
Toxic Spikes
Explosion
Gyro Ball
Rapid Spin
Amazing Supporter and Rapid Spinner. Sets up Toxic Spikes to help the Crocune Sweep a bit more. Rapid Spin clears away opposing Toxic Spikes, Stealth Rocks, etc. Explosion to deal massive damage. Gyro Ball deals decent damage against Dragon Dancers, and speedy Sweepers.

Farinella @ Choice Scarf
4 Def/252 SpA/252 Spe
Flash Fire
Rash
Flamethrower
HP Grass
Dragon Pulse
Earth Power
My Revenge Sweeper. Great type coverage overall. I picked HP Grass > Explosion because how badly Vaporeon screws this team up. Dragon Pulse for opposing Salamence. Perfect with Celebi and Suicune, because of the great type coverage complimenting each other.

Adamant
U-Turn
Bullet Punch
Pursuit
Superpower
I lacked a Physical Sweeper, so I just added him in for denting into teams. Combo with Heatran if I U-Turn expecting a fire attack, however if they go EQ instead when I switch into Heatran, QQ. Pursuit punishes Ghosts and Psychics. Superpower WRECKS Blissey. Usually if I predict EQ coming along when I U-Turn, I switch into Salamence.

Piede @ Life Orb
16 Atk/240 SpA/252 Spe
Intimidate
Naive
Flamethrower
Brick Break
Draco Meteor
Earthquake
I love switching in this guy via Scizor's U-Turn. Draco Meteor is pretty much going to OHKO or almost OHKO any pokemon in the current meta. Flamethrower to scare Ice types. Brick Break to damage Darks, and breaks Reflect/Light Screen. He's a lethal Wall Breaker.
I hope you think that this team is good!
