(Sorry; I misread and thought it said OU instead of UU)
Anyway:
- Give Heracross Choice Scarf OR Flame Orb & Guts. You already have a Moxie Sweeper in Honchkrow.
- Make Kingdra a special sweeper. It has a better special movepool.
- Why would you choice a Honchkrow and give it Confuse Ray? It's also really frail so it needs to sweep ASAP, rather than waste time inflicting a status. Either take off the Band and give it Life Orb + Roost, or give it a Choice Scarf since its slow for UU.
- Replace Abomasnow. It's adding nothing to this team by buffering everyone with Hail. Why is it even there? It just means that your entire team now has 3 stealth rock weaknesses.
- Rivalry is a horrible ability for Nidoking. Sheer Force, however, is a brilliant one, because it means it won't take Life Orb recoil on moves that have a secondary effect. And he has a lot of moves with secondary effect.
Chandelure @ Leftovers
Ability: Flash Fire
EVs: 72 HP, 252 Sp. Atk, 184 Speed
Nature: Modest
- Substitute
- Fire Blast
- Shadow Ball
- Will-O-Wisp/ Energy Ball
NB: the current Chandelure set is okay, but Chandelure is considered slow in OU, and also having low HP, so you might get KO'd before you even have a chance to set up. My suggestion is to scarf Chandelure, but I already suggested Scarf for your Heracross.
Heracross @ Choice Scarf
Ability: Guts/ Moxie
EVs: 252 Atk, 252 Speed, 4 HP
Nature: Adamant
- Close Combat
- Megahorn
- Stone Edge
- Sleep Talk/ Night Slash
Sleep Talk means Heracross can be your sleep absorber, or Night Slash for more coverage. I just like Guts better because if you're burnt by something like Cofagrigus, you're going to need a lot of Moxie boosts to put a dent anything. Then again, Cofagrigus would change your ability anyway...
Kingdra @ Life Orb
Ability: Swift Swim
EVs: 252 Sp. Atk, 252 Speed, 4 HP
Nature: Modest
- Surf
- Ice Beam
- Dragon Pulse
- Rain Dance
I don't see the point of Rain Dance + Dragon Dance. They're kinda redundant together imo.
Honchkrow @ Life Orb
Ability: Moxie
EVs: 252 Atk, 252 Speed, 4 HP
Nature: Jolly
- Sucker Punch
- Brave Bird
- Pursuit/ Superpower
- Roost
Superpower is for Steel types, which will wall you otherwise. Since your team is hyper offensive, you need coverage on all your Pokemon, because switching out can mean something getting KO'd.
Nidoking @ Life Orb
Ability: Sheer Force
Nature: Timid
EVs: 252 Speed, 252 Sp. Atk, 4 HP
- Earth Power
- Ice Beam
- Flamethrower/ Fire Blast
- Thunderbolt
Sheer Force is a really great ability. Never mind that Nidoking has a slightly higher attack than sp. atk, with Sheer Force & Life Orb, Earth Power will do more than Earthquake. All the elemental moves give superb coverage as well as full Sheer Force abuse.
As your team stands, it's hyper offensive. You have 2 Stealth Rock weaknesses and no spinner. You also have no walls/ tanks, meaning switch in will be difficult. You also have no scout. Nothing here's really fast enough (except Scarf Heracross) to lead the team.
Suggestions
Tank
Swampert @ Leftovers
Ability: Torrent
EVs: 240 HP, 16 Atk, 252 Def
Nature: Impish
- Stealth Rock
- Scald/ Waterfall
- Toxic/ Earthquake
- Roar
Swampert makes a good defensive switch in. It has only one weakness, Grass, which can be dealt with by Chandelure/ Honchkrow.
Bronzong @ Leftovers
Ability: Levitate
EVs: 252 HP, 252 Def, 4 Sp. Def
Nature: Relaxed
- Stealth Rock
- Gyro Ball
- Toxic
- Earthquake
Bronzong is the classic set up Pokemon. Great typing, with the addition of Levitate meaning it only has one weakness. Abysmal speed is made up for with the use of Gyro Ball.
Wall
Cofagrigus @ Leftovers
Ability: Mummy
EVs: 252 HP, 252 Def OR Sp. Def, 4 Sp. Atk
Nature: Bold OR Calm
- Will-O-Wisp
- Pain Split
- Shadow Ball
- Haze
Haze is an unbelievably useful move, especially when facing jerks like Suicune, ever popular in UU, which will just use Calm Mind on you the entire day. Haze hits even when your opponent is behind a substitute, unlike Clear Smog.
Downside to Cofagrigus is it has barely any offensive presence if you use it for walling purposes.
Scout
Mienshao @ Life Orb
Ability: Regenerator
EVs: 252 Atk, 252 Speed, 4 HP
Nature: Jolly
- Fake Out
- Hi Jump Kick
- Stone Edge
- U-Turn
If you want to keep things hyper offensive, Mienshao makes a great UU lead. Fake Out to see what your opponent is holding, then U-Turn out for a more suitable Pokemon if things look rough.
