(ST, means Smogon Tiers )

Ocean Neon (Tentacruel) (M) @ Black Sludge
Trait: Liquid Ooze
EVs: 252 HP / 4 Def / 64 SAtk / 188 SDef
Bold Nature (+Def, -Atk)
- Toxic Spikes
- Rapid Spin
- Scald
- Acid Spray
My Lead. I gave up using Physical bulk on him, it just didn't work. I've tried it.
Toxic Spikes is my set up to support Gengar, and it generally hurts to anything opposing the rest of the team ( yayz ) Rapid Spin is to spin away any hazards set by my opponents, which has came in handy. Scald is STAB, and can burn physical threats, which is pretty cool. While Acid Spray lowers my opponents Sp Def, Powering up Scald, Forcing switches, or giving another one of my faster pokemon a better chance to take something down.
Pokemon I've tried in his place:
None.
Other moves I've tried:
Muddy Water, Giga Drain, and Ice Beam.
Blue (Latios) (M) @ Life Orb

Trait: Levitate
EVs: 4 HP / 252 SAtk / 252 Spd
Modest Nature (+SAtk, -Atk)
- Psyshock
- Thunderbolt
- Ice Beam
- Draco Meteor
Latios is my power sweeper, and my tank breaker.
He outspeeds a handful of things, nothing with a Scarf normally, but a handful of things, but he hits ridiculously hard, so most things can't take a hit from him. Psyshock is his STAB, with Blissey being common in OU, Psyshock lets him immediately OHKO Bliss. Thunderbolt and Ice Beam are like a package deal these days, providing excellent coverage of tons of types, meaning he can break through walls, tanks, and slower more bulky sweepers better with super effective coverage. Draco Meteor is his " I'm going to switch, or die from Life orb recoil " move, that lets him make a huge blow on whatever is switching into, or trying to take his attack.
Pokemon I've tried in his place:
I tried Deoxys-S, and really didn't get very good results, he can run the same standard things, only better. His role in my team fitted like a glove, better than Deoxys-S's role did.
Other moves I've tried:
None.
Smile (Gengar) (M) @ Life Orb

Trait: Levitate
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Venoshock
- Shadow Ball
- Thunderbolt
- Hidden Power [Fire]
My speedy, but not Scarfy sweeper, who can do quite a dent. Venoshock gets support from Tentacruel, meaning it's going to do a LOT of damage to whatever it hits. Shadow Ball is his standard and reliable STAB, while Thunderbolt takes out flying takes, namely the ones who can't be poisoned, and HP Fire takes out steel types, that are ridiculously common in OU, and can't be poisoned. Gengar normally gets the longest running sweeps because he can stand alone for himself for a while.
Pokemon I've tried in his place:
I haven't, never had any problems with him.
Other moves I've tried:
Hex, and Psychic.
Stash Power (Landorus) (M) @ Life Orb

Trait: Sheer Force
EVs: 4 Atk / 252 SAtk / 252 Spd
Naive Nature (+Spd, -SDef)
- Extrasensory
- Earth Power
- U-turn
- Focus Blast
My Mixed sweeper, Focus Blast is able to take out Skarmory, and U-turn does a little over 50% to Blissey, meaning he can handle himself on both ends with those threats. Anyway, Extrasensory is his Sheer Force + Life orb coverage, it works great, takes out fighting types with Ice Punch, quickly. Earth Power is STAB, and it hits hard, that's about the only way to sum it up. U-turn is for scouting, and hitting something like Blissey or Latias that walls out my special moves hard while switching out to something that can handle them better. Focus Blast is coverage, and my sure fire way to either OHKO, or put a large dent in Skarmory.
Pokemon I've tried in his place:
Gliscor.
Other moves I've tried:
I tried HP Fighting, it didn't work near as well as Focus Blast.
Smash Rave (Ferrothorn) (M) @ Rocky Helmet

Trait: Iron Barbs
EVs: 252 HP / 48 Def / 208 SDef
Relaxed Nature (+Def, -Spd)
- Leech Seed
- Thunder Wave
- Power Whip
- Stealth Rock
This is my favorite Ferrothorn. Leech Seed gets me some great recovery, which is more and more needed due to my Iron Barbs + Helmet troll combo. Thunder Wave slows down things that my sweepers can't outspeed, and more importantly things that don't get poisoned, haven't my opponents team all have status can really get to be a bummer for the average opponent. Power Whip is STAB, lets me get by from Taunters, hit things that I have nothing left to do to. Stealth Rocks is for hazards, that way nothing gets by without having some kind of pain done to them.
Pokemon I've tried in his place:
None
Other moves I've tried:
I used Spikes for a while, but Levitaters and Flying types can be jerks about that. I also used a different EV spread and nature that balanced out my defenses, and I actually found having that extra defense more use full. And last but not least, I had Leftovers instead of a Helmet for a while, but I like my Helmet better.
Never losed (Houndoom) (M) @ Life Orb
Trait: Flash Fire
EVs: 4 HP / 252 Atk / 252 Spd
Lonely Nature (+Atk, -Def)
- Pursuit
- Overheat
- Sucker Punch
- Reversal
Last but not least by any means... Houndoom!!!
Pursuit + Sucker Punch is both STAB attacks, that are deadly together. Sucker Punch can hit with maxed attack before anything that thinks it can take me down has the chance to touch me, while Pursuit can hit anything that I force to switch out ( Fire types mainly, but others too . ) for some hard damage. And things that switch expecting to see Sucker Punch. Overheat is his only special move, it's STAB, and Flash Fire boosts it up to make up for the lack of EVs invested, either way it does serious damage. While Reversal paired with Life orb will eventually do some good damage to my opponent. This dog is my favorite team member.
Pokemon I've tried in his place:
Infernape, Houndoom works better.
Other moves I've tried:
I had Thunder Fang instead of Sucker Punch for the longest time, but Sucker Punch just straight up worked better. Most of the water types I was confronted with, could outspeed me ( Starmie ) or could take the hit with ease, and still KO me ( Tentacruel and Jellicent ). Sucker Punch ended up being the best option.
I'm open to anyone answering the team question, but I'd appreciate if you gave actual good suggestions, gave suggestions for at least half of the team, and not just nature changes, etc.
Comments are appreciated, and of course, up votes are too ;]
And if I said I tried something out, it's probably safe to say you shouldn't suggest it.
