The team I use for OU- it is beyond awesome- (disclaimer; I don't take credit for making it)
Tyranitar@Chesto Berry
252HP/40Atk/216SpD
Careful (+SpD -SpA)
Payback
Earthquake
Taunt
Stealth Rock
A brilliant anti-lead. OHKOs Azelfs and cripples set-ups with taunt. Chesto berry screws up baton pass leads like Smeargle. Main problem is Machamp lead's DynamicPunch, but they are rarely, if ever, seen.
Skarmory@Leftovers
252HP/220Def/36SpD
Impish (+Def -SpA)
Spikes
Whirlwind
Roost
Brave Bird
Walls like crazy. Stops opponents from setting up with whirlwind, and in most games gets off spikes quite easily. And just heals off the damage with roost. Easily takes out the Machamp lead that Ttar has trouble with. Doesn't get trapped by Magnezone because of whirlwind and usually comes in right after Ttar to set up for the rest of the gang. And does it with aplomb.
Rotom C@Choice Specs
252SpA/252Spe/4SpD
Timid (+Spe -Atk)
Thunderbolt
Leaf Storm
Trick
Shadow Ball
Great power and great coverage. There isn't much that isn't OHKO'd or 2HKO'd by Shadow Ball from this thing. Can also come in and use trick on stall team threats (Blissey, Stallrein etc) rendering them useless for the whole match. Counters Swampert, and I can always switch in Skarmory to take a ghost-type attack from the enemy if it comes down to it, the damage is laughable.
Magnezone@Choice Scarf
252SpA/252Spe/4SpD
Magnet Pull
Naive (+SpA -SpD)
Thunderbolt
Flash Cannon
Hidden Power (Ground)
Explosion
The steel-type killer. Traps them with Magnet Pull, then outspeeds them with the Scarf to pretty much always OHKO. Kills Skarmory with a single Thunderbolt. Always has the option of exploding on opponent too, if things get really bad.
Starmie@Life Orb
252SpA/252Spe/4SpD
Natural Cure
Timid (+Spe -Atk)
Hydro Pump
Thunderbolt
Ice Beam
Recover
Really reliable, about the only resistance to fire types aside from Ttar. Not much can take it's STAB life orbed Hydro Pump. Thunderbolt and Ice Beam give heaps good coverage whilst recover is really necessary, because of the Life Orb coupled with Sandstorm. Nearly always manages a KO.
Lucario@Salac Berry
252Atk/252Spe/4HP
Steadfast
Adamant (+Atk -SpA)
Endure
Reversal
Swords Dance
Ice Punch
AMAZING!!!! Can literally take out whole teams if they don't have any priority users left. I normally leave it as my last switch in for a reason. It has saved me soooo many times. Just endure the first hit, get your speed boosted 50% by the salac berry, and then spam a 200 Power Reversal. Or Ice Punch for those bloody ghosts. But I seriously recommend his addition to almost any team!
