Okay so this is a team that I've been testing in OU and it has had it's ups and downs battles, so without further adieu: (Team is 9-7)
Bronzong@Leftovers
Sassy/Levitate
EVs: 252 HP/86 Atk./80 Def./90 SpD.
IVs: 0 Spe
~Gyro Ball
~Earthquake
~Hypnosis
~Stealth Rock
This is my lead pokemon that sole purpose is to set up stealth rocks and then get out. Problems I find with him is that most, if not every other lead outspeeds him, even other Bronzongs and Taunt him so I won't have the chance to set up my rocks. Gyro Ball in conjunction with a zero speed IV makes for a pretty good STAB'ed attack for Bronzong and Earthquake is for even more coverage. Levitate is the chosen ability because most of my pokemon are weak to ground, well actually only one other team mate is weak to ground, lucario. I'm thinking of changing this for a different, faster and more effective lead, maybe Azelf?
Rotom-W@Choice Specs
Timid
EVs: 6 HP/252 SpA/252 Spe
~Shadow Ball
~Thunderbolt
~Hydro Pump
~Trick
This is one of my special sweepers for the team, and he fulfills the position fairly well. One problem that I see with this Rotom form is that it just isn't fast enough, maybe slap a Choice Scarf onto it. Shadow Ball,Thunderbolt are for STAB, Hydro Pump is for a powerful water attack and Trick I haven't used at all so a possible new complete moveset for this guy.
Porygon-Z@Choice Scarf
Modest/Download
EVs: 4 HP/252 SpA/252 Spe
~HP Fighting
~Tri-Attack
~Ice Beam
~Dark Pulse
The Choice Scarf Porygon-Z set from the analysis, this guy has netted some KOs out of my 16 battles so far. Download for the chance that I will get a plus one special attack boost. All of the attack choices are fairly obvious as to why they are there.
Vespiquen@Leftovers
Impish
EVs: 248 HP/8 SpD/252 Def.
~Attack Order
~Roost
~Toxic
~Defend Order
A UU attempt at a mixed wall in OU, it hasn't really proven itself to me in any of my battles so far. Sure it can stall some pokemon out but seeing how hard the pokemon hit in OU I don't think Vespiquen is going to be staying around for long even with support from Defend Order. Suggestions on what to replace this with are needed.
Lucario@Choice Scarf
Mild/Inner Focus
EVs: 40 Atk./216 SpA/252 Spe
~HP Ice
~Close Combat
~Dark Pulse
~Stone Edge
Another fast Choice Scarf mixed sweeper for the team and I believe does it's job perfectly. I don't really see the need for max Speed on it when it has the help of Choice Scarf.
Salamence@Life Orb
Rash
EVs: 120 Atk./136 Spe/252 SpA
~Crunch
~Flamethrower
~Draco Meteor
~Brick Break
Another mixed sweeper for the team, doing his job just as well as a blissey at special walling.
Well that's my team, I know there's not too much comments on the teams' roles and such which is where you guys come in to help me with changes for the team to make it better.
