This was copy-pasted from Smogon. Hence the ****s.

Ubers.

Mewtwo @ Choice Specs
Pressure
EVs: 4 HP/252 Spd/252 SAttk -- Hasty
Pulse Bomb
Shadow Ball
Selfdestruct
Grass Rope

Starter yay. Lols at Brick Break/FP Darkrai, and BB Quaza. Booms when needed.

Forretress @ Leftovers
Strudy
EVs: 252 HP/4 Attk/252 Def -- Impish
Stealth Rock
Rapid Spin
Light Screen
Explosion

It SRs, Spins, pseudopasses, booms, and covers Mewtwo/Giri dark weak, all while providing better defenses than Skarm at the cost of a double fire weak (which Giri takes no problem) and EQ neutrality (grr EQ).

Blissey @ Leftovers
Serene Grace
EVs: 252 HP/104 SAttk/152 SDef -- Calm
Calm Mind
Thunder
Softboiled
Ice Beam

Steals Kyogre's Drizzle to Thunder it back. Wins non-phazing CM wars.

Aruseus @ Leftovers/Life Orb
Multitype
EVs: 204 HP/252 Attk/52 SDef -- Adamant
Swords Dance
Extremespeed
Recover
Shadow Claw

A bit sturdier than the analysis Extremekiller. It might need something over Recover, but I really need it if I use Life Orb. It loses the definate SD+ES OHKO on Mewtwo, but it's still possible.

Giratina @ Leftovers
Pressure
EVs: 252 HP/4 Attk/252 Def -- Impish
Will-o-Wisp
Roar
Dragon Claw
Protect

Covers that triple fighting weak. Roars Tauntless Mew and other stat-uppers. Dragon Claw for attacking.

Lucario @ Leftovers
Humble Heart
EVs: 4 HP/252 SAttk/252 Spd -- Timid
Calm Mind
Pulse Bomb
Dragon Pulse
Shadow Ball

Oh how I've wanted to use this. Dragon Pulse >>> Parukia.

1 Bug weak, 1 EQ weak, 2 Dark weak, 3 Fight weak, 2 Fire weak (one 4x), 2 Ghost weak, 1 Dragon weak, 1 Ice weak.

1 Rock resist (4x), 2 Ghost immune, 2 Ghost resist, 1 Fight immune, 1 Fight resist, 1 Normal immune, 2 Normal resist, 3 Grass resist (one 4x), 1 Electric resist, 1 Fire resist, 1 Water resist, 2 Ice resist, 2 Dragon resist, 2 Psychic resist, 1 Fly resist, 1 Poison resist, 3 Bug resist (two 4x), 2 Dark resist (one 4x), 2 Steel resist.

Counters (because I felt like it):

Aruseus: Lol Aruseus counter. That SD + Shadow Claw/Dragon Claw set is survived by Giri and WoW'd, then Roared. Special gets CMs from Blissey. Might have some problems with other sets.
Darkrai: Blissey can take any non-physical fighting move, which Mewtwo switches into nicely and Pulse Bombs. If they predict the switch and sleep Mewtwo, Blissey can CM up with it, and possibly take FP version with prediction. Lucario can Pulse Bomb it.
Mewtwo: Prediction counters CS as I have a switch in for everything. Giratina can Roar, Bliss CMs.
Blissey: Fat ***** can't take repeated Pulse Bombs or Aruseus Extremespeeds.
Heracross: Extremespeed kills Reversal. Prediction kills CB/CS.
Tyranitar: CB dies to prediction. Anything else faces Lucario. Giratina can take a Crunch and WoW back.
Kyogre: Thunder CMBliss. Mewtwo has a 73.2% chance to survive Surf and 2HKO with Grass Rope.
Groudon: Grass Rope Mewtwo, Giratina, maybe Lucario.
Rayquaza: IB Bliss, WoW Gira.
Mew: Gira Roars, except for Taunt. ****ing Taunt. Mewtwo might be able to KO the recipient on the switch-in. Schemepass can be partially stopped with Blissey if she CMs up while it Schemes.
Lugia: Setup bait for Aruseus/Blissey. WW versions are useless, just switching things around without doing anything.
Ho-oh: Gira takes Fire/Electric attacks and walls their spinner.
Salamence: Blissey for Specs, Giratina for DD/CB.
Manaphy: A ***** with Kyogre, less so with Thunderbliss.
Giratina: Aruseus can set up on CM versions, lacking WoW or Roar. Not so good.
Parukia: Blissey TWaves. Lucario Dragon Pulses.
Diaruga: Can't switch in on Lucario's CM or Pulse Bomb, or Mewtwo's Pulse Bomb. Might have trouble with it. CMBliss can set up with it.
Heatran: CS/CS are the usual, so prediciton.
Wobbufett: Kills Mewtwo, Blissey. Encores Lucario/Blissey/Aruseus setup. Gira can Roar it, and Forry just sets up everything and explodes.
Deoxys(-FR/E): Blissey OHKOs special versions, just be wary of Superpower. Gira takes care of physicals as they lost Shadow Ball.
Deoxys-LG: Aruseus is Knock Off switch in. Forry spins spikes. Might have trouble with statusers.
Lati@s: Blissey CMs with them and Aruseus sets up faster. Mewtwo will survive Soul Dew Dragon Pulse for the 2HKO and I will lol about it.
Shedinja: Aruseus, Mewtwo, Lucario, and Giratina can KO it. Dies to SR.
Forretress: No SR weak, a spinner, and a 4X SR resist. Gira takes predicted booms.
Ludicolo: DIE LUDI. Die to Extremekiller. Except Blissey kinda sucks against it if it has Leech Seed. Which it will.
Exeggutor: Gira resists HP Fire/Solarbeam/Explosion. It has like, **** special defense which is basically death against this team.


And I think that's it. If you spot any flaws, let me know.

EDIT: Switched TWave out for CM on Bliss.

 

[Samson]

well the largest flaws is that this is outdated. a lot of the attack names need to be updated.

 

[Captain Fabio]

Oh... my god!
What have you done to blissy?!

Blissey @ Leftovers
Serene Grace
EVs: 252 HP/104 SAttk/152 SDef -- Calm
Thunder Wave
Thunder
Softboiled
Ice Beam

Special attack? It isn't that great you know.
Keep blissy to what it does best.
Ice Beam

Meh. I like them better this way.

Blissey @ Leftovers

Thunder Wave
Thunder
Softboiled
Ice Beam

Special attack? It isn't that great you know.
Keep blissy to what it does best.
Ice Beam

Lets see:

CMBlissey
- Hits Gyarados
- Covers Togekiss (unless they just BP away from you)
- Covers Manaphy
- Generally has high SA to actually put a hurt on things. I actually run max SA to break Raikou's subs. It really isn't built to absorb physical hits this gen (although I still give it defense). It can hurt Rhyperior on the switch with Ice Beam better than the standard set, possibly 2HKOing it.
- OHKOs Garchomp/Mence
- Covers Suicune
- Covers Azelf (as long as it doesn't Taunt or Explode)
- Skarmory can't set up on you.
- Still covers Raikou.
- Doesn't get stalled by anything non special wall/TTar.
- Covers Non Calm Mind or Focus Punch Dusknoir porbably

SToss Bliss:
- Gets 2 awesome status moves
- Can use Seismic Toss.
- Generally have more HP/Def than CMBliss

It's your pick here.

And that's OU. In Ubers, Blissey literally cannot take a physical hit to save its life. And SToss fails at all the high HP. It needs to go on the offensive more.

In fact, that whole list was for CMBliss, far more effective. I might switch out TWave for it since I have Serene Grace for paralysis.
