Modest Nature
EVs: 240 HP / 164 Def / 92 SpD / 12 SpA
Ability: Trace
Discharge
Ice Beam
Magic Coat
Recover
Over and over again, people have asked me the question "Why don't you evolve your Porygon2 ? Its Special Attack isn't nowhere near Porygon Z's", well, Upgrade THIS!. Porygon2 has been able to screw up a lot of leads while still being able to maintain its own wellbeing with Recover and Magic Coat.
Choosing Porygon2 didn't take long. I was in a roulette battle leading with this and my opponent had a Bronzong out, he used Hypnosis and I used Magic Coat, his Bronzong ended up being put to sleep while Porygon2 was still at full HP. I then find out that Porygon2 is surprisingly bulky and I use that to my advantage when things like Garchomp and Weavile switch in.
The moveset is the one from the analysis. Discharge's 30% accuracy makes Deoxys-S think twice after switching in, Ice Beam for pure coverage, Recover for, well recovery and Magic Coat for sending predicted status back at the user.
Bottom Line
Porygon2 has been a nice lead of my team, however, one would say that a Gengar would own this, in fact, only Specs'd versions would get the jump on me, in this case, I switch to the next member of my team to remove that asshole from play (Life Orb Gengar has only a 15% chance of OHKOing with Focus Blast). I'll mainly setup a Magic Coat since my opponent might try to outpredict me, thinking that Porygon2 will flee at the thought of getting hit in the face with Focus Blast and use Hypnosis.

Spiritomb @Leftovers
Careful Nature
EVs: 252 HP / 72 Atk / 116 SpD / 68 Def
Ability: Pressure
Pursuit
Taunt
Pain Split
Hypnosis
So, what if that Gengar uses a Specs-boosted Focus Blast and or, if that 15% chance of an OHKO becomes a reality? Well, I have this, Spirtomb. Spiritomb will catch a fleeing Gengar and OHKO with Pursuit, if not that, screw up some sweepers who tend to setup on Spirtomb. The EVs allow Spiritomb to catch a fleeing Azelf with Pursuit, giving it a maximum of two attacks when it comes back out.
The choice of Spiritomb came down to what I needed the most, protection from special sweepers and Gengar. Spiritomb provides both and an almost reilable soruce of recovery as well.
The moveset is a bit "meh" from the analysis. Pursuit catches things who flee from Spiritomb while Taunt screws with sweepers attempting to setup on Spirtomb and Pain Split is just there for recovery reasons.Hypnosis allows me to shut down sweepers on the spot as well as bulkier things who can outstall Spiritomb.
Bottom Line
Spiritomb had been a wonderful counter to Weavile and Gengar while still being able to kill of sweepers with the great ability to Taunt them and/or put them to sleep.

Dusknoir @Leftovers
Careful Nature
EVs: 252 HP / 252 SpD / 4 Def
Ability: Pressure
Shadow Sneak
Mean Look
Will-o-Wisp
Pain Split
The second roulette choice- DuskTrap. In case Bronzong is running around on the other team, or, if I want to kill off Blissey, Dusknoir is here. The objective of this thing is simple, get in, trap whatever it can and outstall it.
The choice of Dusknoir came from how I saw how it was able to to support my team with Will-o-Wisp, trap and kill off a lot of walls with Pain Split and Will-o-Wisp running for it. I started running this outside of roulette battles and it managed to do the same thing to all of the walls I faced, it trapped them, and sapped thier HP away with Will-o-Wisp while chipping away at their HP with Shadow Sneak.
The moveset is pretty basic, Mean Look for trapping. Will-o-Wisp for extra damage, overlapping any Levtovers recovery. Shadow Sneak for extra damage and Pain Split for healing.
Bottom Line
Dusknoir is one of the few trappers with so many reistances and immunities, that's what I've been using to my advantage. Dusknoir also works with Porygon2 in a way if my opponent pulls that almighty tatic, GyaraVire in which my opponent sends out a Gyarados, first, predicts an electric attack and switches to Electivire. Dusknoir isn't 2KO by anything, but a critical hit, so, if Electivire comes in to absorb Discharge, it'll think twice about staying in on Dusknoir. As an added Bonus, Dusknoir outspeeds any form of Bronzong meaning that it can trap Bronzong in while steadily wearing its HP down.

Jirachi @Leftovers
Timid Nature
EVs: 252 HP / 224 Spe / 32 SpA
Ability: Serene Grace
Psychic
Hidden Power [Fighting]
Calm Mind
Substitute
The main sweeper of this team. Jirachi is one hell of a SubMind sweeper with its base 100 speed, HP and defenses, however, its typing is a bitch when Garchomp gets in. The plan for this thing is: Get in, Sub up and sweep. I always get up a Substitute, first, for the main reason that if I switch Jirachi in, someone will switch whatever they had in out and thus, Jirachi needs a bit of protection if one its main threats gets in, or, if something faster with status gets in. The EVs are a bit mixed, max HP in case is things with Seismic Toss, 224 in speed to outspeed any positive base 95's such as Lucario and Houndoom, the rest goes in Special Attack.
The choice of Jirachi was also in a roulette battle :/. I used to use a very simular SubMind Jirachi, however, I added Hidden Power Fighting and the coverage was basicly maxed out. It hit Tyranitar and Weavile while Psychic would be the main choice of an attack, maxing out at a base 142 attack, outclassing a x2 SE Hidden Power Fighting.
The set is self explanitory. Substitute to protect it from damage and stauts, Calm Mind for sweeping purposes. Psychic and Hidden Power for nice type coverage and attacking power.
Bottom Line
Jirachi is one heck of a Calm Mind sweeper. Even without a Calm Mind, it's still a monster when it's behind a Substitute. The coverage is blocked by Psychics, however by the time Jirachi gets in, Dusknoir and Spiritomb will have both wiped them out.

Vaporeon @Leftovers
Bold Nature
EVs: 188 HP / 252 Def / 68 SpA
Ability: Water Absorb
Surf
Ice Beam
Wish
Roar
I needed some support and Vaporeon was just the thing, stopping Infernape in its tracks and giving Wish support to the rest of my team. Phazing is also one of Vaporeon's favorite jobs.
Choosing Vaporeon wasn't really hard. I couldn't find any other Pokemon with the ability to tell Suicune and Infernape to "screw off" with Wish and Roar at thier disposal as well.
The moveset is standard right down to the point. Surf for STAB, Ice Beam as another attacking option and coverage, Wish for support and healing and Roar for Phazing.
Bottom Line
Vaporeon gets right down to the point everytime it's out. It either kills something, Roars something, or, setup a Wish for the rest of my team. I can actually see something replacing this, though.

Yanmega @Life Orb
Modest Nature
EVs: 252 SpA / 252 Spe / 4 HP
Ability: Speed Boost
Bug Buzz
Hidden Power [Ground]
Air Slash
Hypnosis
Now, we get to the last of the crowd, the clean up sweeper, Yanmega is just beastly with a Life Orb and the coverage is awsome as well. Azelf used be in this spot, however, after several battles with this, Yanmega has been a proud member of my team.
When I was running a few battles without Spiritomb and Azelf, I needed two fillers. I used a Yanmega that was in my PC for a while. Yanmega was able to blow away the rest of the game with Speed Boosted Bug Buzz's and Air Slashes while getting its other needed coverage against Heatran and Metagross with Hidden Power Ground, so, I decided to replace Azelf with this.
The moveset is a bit easier to run late game. Bug Buzz an Air Slash both get STAB and do major damage to switch ins while Hidden Power Ground hits those bulky steels like Metagross and Heatran hard as hell. Hypnosis was a filler at first, however, with most of the things I put to sleep with Spiritombs's filler (Gengar) being KO'd by the time Yanmega gets out, Hypnosis has been of great use, being able to put things that use moves like Sucker Punch to sleep, or, putting things that can't be OHKO'd by Air Slash, Hidden Power, or, Bug Buzz to sleep so they can't even touch Yanmega.
Bottom Line
After proving its worth to me, over and over again, Yanmega is just a proud staple of my team. Now, what pushed me to actually making the switch was the fact that once it gets in and KO's something, it gets an automatic speed boost, placing its speed at 433, putting it above ScarfCross and those trying to outspeed it. That's some mad speed, isn't it? Now, combine a 473 Special Attack and a 433 Speed after one turn of it being out and you have a late game sweeper. Also, Stealth Rock won't pose a threat to it. Although half of its Health will be stripped away, Yanmega still has 5 turns of unprotected fun which is mainly all I've been needing late game.






Well, I guess that's the team.
Problems
Blissey might have a nice time with my team, although, Dusknoir is the one who traps and kills it most of the time. Jirachi can use it for setup fodder with its 101 Subs and hope for a Special Defense drop after the first few Psychics. Spiritomb also has Taunt, which is pretty good in case Blissey carries Thunder Wave, or, Toxic.
Another Dusknoir could pose a problem, however, if I can predict right, I can score a status on if with Spiritomb, or, my Dusknoir. From there, Jirachi can use it as setup fodder.
Suicide leads also take a huge chunk out of my team, however, Spiritomb can catch suiciding Azelfs with Pursuit. Like Sucker Punch, it has a 1/13 chance of OHKOing Azelf since the base Power is the same. Suiciding Infernapes are handled by Dusknoir who can trap them while wearing them down with Shadow Sneak.
If Vaporeon falls, CroCune can run rampant on my team, however, I severely doubt Vaporeon will be out be that time. Spiritomb also has Taunt, so, Suicune can be status'd and not sleep for a while being locked on Surf.
