Disgusted with my utter lack of any sort of talent on the OU ladder, I thought I'd try UU on for size. With the recent banning of Hippowdon from the tier, I'm thinking a team like this is going to have a much better chance of shining. Without further ado...
THE MANLY MEN OF UNDERUSED
Victini @ Choice Band, Adamant, Victory Star
4 HP/252 Atk/252 Speed
~V-create
~Fusion Bolt
~Zen Headbutt
~U-turn
U-turn is there to scout for the right time to spam V-create. Other moves are for coverage, though Zen Headbutt has a nice flinch chance.
Donphan @ Leftovers, Adamant, Sturdy
252 HP/252 Atk/4 Def
~Earthquake
~Ice Shard
~Rapid Spin
~Head Smash
Victini always appreciates spin support, and on top of Donphan being one of the best spinners in the tier, 120 attack and Sturdy means he's one of this team's two checks to Azumarill. Head Smash grants EdgeQuake coverage, but is only to be used in emergencies due to the recoil compromising his bulk.
Dugtrio @ Life Orb, Jolly, Arena Trap
4 HP/252 Atk/252 Speed
~Earthquake
~Stone Edge
~Sucker Punch
~Substitute
Sadly, Fake Out beats Sucker Punch, so this guy is going to have to watch out for Ambipom. Otherwise, he's a great trapper and killer, using Sucker Punch with 372 speed to try to top Azumarill, especially the CB variety that's already locked into Aqua Jet, not to mention that a frail mon like this is a very good lure for the opponent to try to attack and kill it.
Rhyperior @ Choice Band, Adamant, Solid Rock
160 HP/252 Atk/96 Speed
~Earthquake
~Stone Edge
~Aqua Tail
~Megahorn
This guy kills everything that dares to stay in, simple as that. Pick the right move and watch stuff take heavy damage. The idea is to force the opponent to expend a significant amount of resources trying to knock this behemoth out, if wiping him out entirely isn't an option. Bulky special-attacking waters such as Milotic are a huge issue, though.
Medicham @ Choice Band, Adamant, Pure Power
4 HP/252 Atk/252 Speed
~Hi Jump Kick
~Zen Headbutt
~Thunderpunch
~Ice Punch
As incredible as it may seem, this guy has MORE attack power than Rhyperior, but trades away bulk for speed, reaching 259. HJK is just pure devastation to anything that can't manage to dodge it, then you have secondary STAB and BoltBeam as coverage. The cleaner and sweeper.
Flygon @ Choice Scarf, Jolly, Levitate
4 HP/252 Atk/252 Speed
~Outrage
~Earthquake
~U-turn
~Stone Edge
I was thinking Staraptor for this role, but then I decided I wanted EdgeQuake resistance as well as fantastic revenge killing power without resorting to priority. Outrage works very well with Choice items, since you're locked into that move anyway. The only drawback in this case is, you can't switch. U-turn is again here to scout, ease prediction, wear down would-be counters and try to maintain momentum. This guy may seem like an inferior Garchomp, but Levitate means he's in a class by himself.
