A New UU Team I made.
Venusaur @ Choice Scarf
Timid
56 HP/252 SpA/200 Spe
Sleep Powder
Leaf Storm
Hidden Power [Ice]
Sludge Bomb
Venusaur is a great lead. Sleep Powder is one of the only reliable sleep moves, especially now that hypnosis got an accuracy drop. Leaf Storm helps to hit things hard.
Grumpig @ Leftovers
Calm
252 Hp/160 Def/96 SpD
Rest
Sleep Talk
Psychic
Signal Beam
Special Wall. Platinum gave Grumpig Signal Beam, a slightly stronger option over hidden power [bug] with a chance of confusion. Helps by absorb status for my team and wall special attackers not named Venemoth. Thick Fat is useful, too.
Steelix @ Leftovers
Impish
252 HP/120 Atk/136 SpD
Earthquake
Gyro Ball
Stealth Rock
Roar
Steelix, the standard physical wall of UU. Brings Stealth Rocks to my team, but quick a few annoying weaknesses too, particularly fighting and fire.
Weezing @ Leftovers
Bold
252 HP/252 Def/4 SpA
Flamethrower
Thunderbolt
Will-o-wisp
Pain Split
Handles things Steelix can't, particularly fighters, and much better than Drifblim and Rotom in my opinion. Helps with its resists and by spreading status.
Altaria @ Leftovers
Careful
252HP/4 Atk/252 SpD
Dragon Dance
Outrage
Earthquake
Roost
Ugh, my physical sweeper. Dragon Dances to boost it attack and speed, sweeps and then roosts to recover life orb (and stealth rock) damage. I don't think its working well for my team, but I can't find anything to fit in its place.
Clefable @ Life Orb
252 HP/152 Def/104 SpA
Calm Mind
Thunderbolt
Ice Beam
Soft boiled
I love this thing. Magic Guard prevents life orb and entry hazard damage, which is great, and it can absorb will-o-wisps and toxics, calm mind up and sweep, healing when necessary. Fighting Pokemon stop this though, but Weezing takes care of them.
EDIT: My main problem I think is with Venemoth.
