Ou. No weather. No tricks. No bollocks.

Question

This is a team consisting if two very popular cores put together, in my hopes to be a "super core". It's CS but I have used it with success in regular ou so far.

Rotom w leftovers
Nature: modest
252 hp 100 def 56 sp atk 100 sp def
Ability: levitate
Will o wisp
Pain split
Volt switch
Hydro pump

Bulky attacker, supporter and rain check. All in one.

Heatran leftovers
252 hp 48 def 200 sp def 8 spd
Nature: calm
Ability: flash fire
Lava plume
Stealth rock
Toxic
Roar

Support heatran. Stealth rock status, phazing, the works.

Celebi leftovers
252 hp 236 sp def 20 spd
Nature: calm
Ability: natural cure
Giga drain
Psychic
Recover
Thunder wave

Special wall. Heatran/conkeldurr love paralysis support. Fighting check. Completes the celetran core.

Scizor choice band
252 hp 252 atk 4 sp def
Nature: adamant
Ability: technician
Bullet punch
U turn
Superpower
Pursuit

Not much needed to say here. I think you've all seen a choice band scizor before.
Completes the little volt turn thing going on here.

Conkeldurr: leftovers
Evs: 132 hp 252 atk 124
Adamant
Nature: adamant
Ability: guts/iron fist
Bulk up
Mach punch
Drain punch
Stone edge

The sweeper. Bulky, like his team mates, and with great power. He has proved himself quite the powerhouse in his battles so far. Stone edge is for volcarona, but also hits thundurus, dragonite and the like.
:

Hydreigon choice scarf (replaced by garchomp)
Evs: 4 atk 252 sp atk 252 spd
Nature: naive
Ability: levitate
Draco meteor
Dark pulse
Flamethrower
Uturn

That's the current roster. To be clear: THE NEXT POKEMON IS A FORMER MEMBER!
Former member

Garchomp: life orb
Evs: 4 hp 252 atk 252 spd
Nature: jolly
Ability: rough skin
Outrage
Earthquake
Stone edge
Stealth rock

Well that's it. Open to all suggestions, comments, and criticism
I want to thank all you wonderful guys for your awesome advise.

Actually, the scariest type of Hydreigon around is Sub + 3 attack Hydreigon, which can Sub up before Breloom (usually) tries to Spore and gain himself some easy SD boosts, then proceed to KO it with a Fire Blast/Flamethrower. as for Mamo, i have yet to see a dragon in OU take it down without taking heavy damage from ice shard.
And btw, i see Hydreigon all the time... idk what nubs i battle, or idk where you ladder Enoch xD

Hmm.. Hydreigon has seen fewer use of late, but tbh most teams need mamo and technicloom counters anyway. Being slightly more careful isn't that much of a problem xD and Hydreigon  with scarf outdoes a lot, spamming power draco's every time it comes out puts dents into any team, making them very easy to pick of later if draco doesn't KO auto. I just wish Hydreigon had better speed without scarf, cos then that massive coverage can work with LO to do Nuclear bomb  type damage to virtually all the meta game. And mamo doesn't enjoy a Focus blast to the tusks anyway xD

Me too breaker me too. But with U turn and moveset versatility Hydreigon is still pretty darn scary.

Mamo = Fat (slightly OP) Mammoth. There should be a BL between Ubers and OU for Mamo.
