Swampert is my lead pokemon who sets up stealth rock and then just can deal a good amount of damage and even sometimes knock out other leads and switch outs.

Scizor is one of the four sweepers on my team a basic set setting up swords dance and dealing significant damage to the opposing pokemon with bullet punch and for those who resist bullet punch brick break and x scissor and with 31 speed ivs it out speeds if not ties all other adamant scizors

Heatran@ life orb

Ability:Flash fire
Nature:Timid
Evs 252 spA/252 Spe/4 HP
Moveset
-Fire blast
-Earth Power
-Hidden Power (electric)

Heatran is another of my four sweeper taking out Gyrados and other water types with his hidden power that threaten him and a great bluff for Scizor swithing him in to steal a flash fire boost.

Azelf@ Choice Scarf/ Choice Band

Ability:levitate
Nature:Adamant
Evs 252 Atk/ 252 Spe/ 4 HP
Moveset
-Zen Headbutt

Azelf is my choice of choice sweeper while i interchange the two choice items depending on wheather i want speed or power despite azelf already having great speed and attack.

Zapdos@ leftovers

Ability:Pressure
Nature:modest
Evs 252 SpA/ 252 Spe/ 4 Def
Moveset
-Thunderbolt
-Heat wave
-Hidden power (Ice)
-Roost
Zapdos is the fourth and final sweeper who also can swith into water types that threaten my Heatran. deal big damage to the foe and just roost it off (in other words he is my healing sweeper).

Dusknoir@ Leftovers

Ability:Pressure
Nature:Careful
Evs 252 HP/252 Def/ 4 SpD
Moveset
-Shadow Sneak
-Will-O-Wisp
-Fire Punch
-Shadow Sneak
Dusknoir is the wall of my team being mostly physical due to his access to Will-O-Wisp crippling physical sweepers. With his 135 defence and special defence he walls more than just physical. Pain split is also and awsome move crippling pokemon from full health while healing Dusknoir.

As much as I like Zapdos and Dusknoir, you can probably merge both of them into a Rotom, which covers both of their roles in one, leaving space for another team member. A life orb subsplit Rotom is very powerful and effective, 2HKOing most of OU. It also provides a check to Adamant Luke, Agiligross, and bulky Gyara.

-Pain Split
-Hidden Power Ice / Hydro Pump / Will-o-Wisp

(Or 252 HP and lefties and Wow if you want more defense)

For the extra space, you are very much weak to Starmie and fire attacks in general. I would try a DDchesto Kingdra out in the free space. Kingdra is one of the few "safe" switches into Starmie, and can proceed to set up, rest of damage, sweep. It can also absorb status fairly well and turn the tables with rest.

144 HP / 160 Atk / 40 SpD / 164 Spe
-Dragon Dance
-Waterfall
-Outrage
-Rest

Lastly I would recommend a more solid revenge killer than Azelf. Azelf is pursuited easily and lacks the bulk to survive long enough. Jirachi can revenge kill top OU threats and flinch your opponent to death, not to mention switch into things like Shaymin, Gengar, and Starmie as a last resort.
