I decided to make a UU team with only UU Pokemon that I've never before used (or at least not recently) so this team might be kind of bad, but on Showdown it's going 3-3 (that surprised me) so it's kind of good, I hope. Anyway here's the team:
Mienshao @ Life Orb

Trait: Regenerator
EVs: 252 Spd / 252 Atk / 4 HP
Jolly Nature
- Fake Out
- U-turn
- Hi Jump Kick
- Stone Edge
I would rather have Ambipom here, but since it's a team of new UU's, well, Mienshao will have to do. But really, Regenerator makes Mienshao totally worth it. Maybe on a future team I'll have both of them xD Anyway, Mienshao works in the same way Ambipom does. Fake Out gets me free damage, U-Turn is for scouting, Hi Jump Kick is risky but worth it, and it's also my STAB move, and Stone Edge is for coverage.
Xatu @ Light Clay

Trait: Magic Bounce
EVs: 252 Def / 252 HP / 4 SDef
Calm Nature
- Thunder Wave
- Roost
- Light Screen
- Reflect
Xatu is ok, I guess. The good thing is that I never have to worry about Taunt. Xatu is also the perfect Sableye counter, it can't do anything to it. Thunder Wave is to cripple opponents, Roost for free healing, and Light Screen and Reflect are to help the team. I don't know if I should have calm Mind and Psychic over those two moves, though. Also, I'm considering U-Turn.
Umbreon @ Leftovers

Trait: Synchronize
EVs: 252 SDef / 252 Def / 4 HP
Impish Nature
- Wish
- Heal Bell
- Toxic
- Payback
Umbreon is pretty cool, the bulk is really helpful. Wish is to support the team members for the heal, and the reason I don't have Protect is because, well, I figure the bulk will save me. I have a feeling that I'll regreat that though. I don't know, it's working fine right now :P Heal Bell is to get rid of the annoying status, Toxic is for some extra attack, and Payback is some extra damage.
Mismagius @ Lum Berry

Trait: Levitate
EVs: 252 Spd / 252 SAtk / 4 HP
Timid Nature
- Nasty Plot
- Shadow Ball
- Substitute
- Thunderbolt
My epic sweeper, if set up right. Lum Berry is for all the T-waves that come my way, just in case I can't set up Sub first Thunder wave can just wreck this guy. Well anyway Nasty Plot is just there, though I'm not sure weather to replace this with Calm Mind. Shadow ball and Thunder Bolt covers each other up nicely.
Gligar @ Eviolite

Trait: Immunity
EVs: 252 Def / 252 HP / 4 Atk
Impish Nature
- Stealth Rock
- Toxic
- Substitute
- Earthquake
I've decided to make this a full out Defensive Pokemon, which means I won't even t hink about surviving Surfs and that, but if a Pokemon like Heracorss comes in, I'll be able to take some hits while Toxicing it. EQ is my only attack, though I don't use it much.
Heracross @ Choice Scarf

Trait: Moxie
EVs: 252 Atk / 252 Spd / 4 HP
Adamant Nature
- Close Combat
- Megahorn
- Stone Edge
- Facade
My scarfer and sweeper. Close Combat is just needed on this guy, it pwns, if I can get some Moxie boosts in. Megahorn is some extra coverage, also it's a nice STAB. Stone Edge is coverage, and Facade is just in case I come in on a Will-O-Wisp.
