So my team works as just a highly offensive OU team, with some support. I've done some Shoddy with it and I've noticed that it fairs pretty well. Please take a look. =]
Edits in green.
Thought Process:
So Scizor is probably my favorite Pokemon and there really isn't a better revenge killer, in my opinion, than him. He's not much to work a team around, but I knew I had to have him on my team.
Next, I needed to add a Stealth Rock lead, so I chose Heatran. He gets the job done, has Explosion if shit goes wrong, and provides my team, and Scizor most importantly, with good fire coverage.
I added Breloom next because I really wanted a star for my team, and I really feel like Breloom really gets the job done. His ability to support my team (fear switching the Spore) makes him incredibly offensive and a great threat, especially to Tyranitar who counters my Heatran.
Next, I wanted to add Empoleon as a Special Sweeper, even more so late-game due to his Petaya Berry. He also could counter opposing Heatran, providing a good switch for Breloom and Scizor.
After doing some Shoddy Battle, I just wasn't getting the results I wanted from Empoleon (or maybe I just wasn't using him right). Out of the battles I fought, he could maybe take one opposing Pokemon out, but also suicide himself, making him the perfect kamikaze. I decided to add a Tyranitar to my team before changing Empoleon for Togekiss and I found that it works nicely. Tyranitar covers Starmie and Gengar well (as does Scizor) but leaves me with a ground and fighting weakness, which is where Togekiss comes in. It can handle fighting-types well and also provides a much need EQ resist on my team.
Lastly, I added Vaporeon for the water-type coverage as well as having a wisher on my team for extra support.
I took the advice of Nosferalto and changed my Togekiss to a Gliscor and it's great. It takes Earthquakes and Fighting-type moves like a freaking pro. He's here to add resistance to my team basically.
In-Depth:
Heatran @ Shuca Berry
Timid / Flash Fire
252 SpA / 4 SpD / 252 Spe
~Fire Blast
~Stealth Rock
~Earth Power
~Explosion
Heatran's purpose is to put up a Stealth Rock and then either switch out, explode, or deal with their lead. After many of Shoddy Battle, I've found that it can deal with most OU leads except Swampert, so I switch out for him. I've found that he does surprisingly well against anti-lead Dragonite, 2HKOing them with Fire Blasts. Obviously, if he's still alive and I'm having trouble with a certain Pokemon, I'll explode on them, but that leaves me with a big problem on my team. See, I've found that when using him to Explode, I'm left without a Fire counter to two of my main sweeping Pokemon which really hurts me. It's made me contemplate whether Taunt is more beneficial, but right now I still run Explosion.
Scizor @ Choice Band
Adamant / Technician
248 HP / 252 Atk / 8 Spe
~U-turn
~Bullet Punch
~Superpower
~Pursuit
Not much really to explain here since you all know how a CB Scizor works. I either go in for the revenge kill with Bullet Punch, U-turn scout, or scare/kill Gengar, Starmie, and other ghost/psychic Pokemon with Pursuit. I found his Pursuit to be a lot more threatening than Tyranitar's just because of the resistances Scizor has to almost anything that would be scared of his Pursuit.
Breloom @ Toxic Orb
Jolly / Poison Heal
12 HP / 252 Atk / 244 Spe
~Spore
~Focus Punch
~Seed Bomb
~Substitute
Oh how I love Breloom. Spore is so freaking deadly it's not even funny. What I usually do with my Breloom is switch him in on a counter and work from there. He's either going to stay in, take the Spore, switch out and take the Spore, or switch into something who can absorb it like Celebi. So far I haven't ran into someone who can absorb so I don't know how to handle that, but Breloom can go on a nice sweep of just sporing, killing, sporing killing, while obeying the ever so important Sleep Clause.
Gliscor @ Leftovers
Jolly / Sand Veil
252 HP / 4 Def / 252 Spe
~Taunt
~Earthquake
~Roost
~Ice Fang
Let it be said, Gliscor is above and beyond better than Togekiss. First off, he doesn't get owned by Sandstorm and gets the added evasion bonus with Sand Veil. After doing a lot of Shoddy with this team, Gliscor is excellent. I can switch into him reliably whenever someone tries to Fighting-type/EQ counter Scizor, Heatran, and Tyranitar and then strike back with Earthquake. I had been using Toxic over Ice Fang, but I just started using Ice Fang and I find it pretty good. It allows me to get rid of Dragon-types more reliably.
Tyranitar @ Choice Scarf
Jolly / Sand Stream
4 HP / 252 Atk / 252 Spe
~Stone Edge
~Crunch
~Pursuit
~Earthquake
Tyranitar, aside from being another sweeper and countering Fire Pokemon, adds to the whole strategy of my team and just swapping as much as possible. He's absolutely amazing for predict switching, especially on Physic or Ghosts who will just get raped by my Pursuit. Also, while Togekiss is handling Infernape, Ttar is taking Heatran on. With two of the most common fire-types nullified on my team, Tyranitar is whole-heartedly welcome.
Vaporeon @ Leftovers
Bold / Water Absorb
188 HP / 252 Def / 68 Spe
~Wish
~Protect
~Surf
~Hidden Power Electric/Ice Beam
Vaporeon's job is pretty clear cut. She wishes other Pokemon or just Wish/Protect stalls herself so I can scout a little. She also is my water-type to handle threats accordingly, like Aerodactyl and other rock/ground types. The problem though is that I found I can't handle Gyarados or Kingdra well without Empoleon and his Ice Beam, although he wasn't that great at it to begin with. A weakness I see with my team is the lack of Dragon coverage, making me want to take Ice Beam over HP Electric, but with Gyarados so common in the OU tier, I think a 4x HP Electric would be way more appealing.
