The Uber metagame is something that most players "shy" away from because of the raw power of Ubers. Of course some "noobs" use Ubers and challenge people only to get destroyed by skilled players and their OU teams. Ubers have the power to OHKO every single pokemon in the game (besides other Ubers) given the chance. Specs-Kyogre is a beautiful example. So when making an Ubers team you need to prepare yourself against large threats. Those threats being: BP Mew, Darkrai, Random Scarf-Users, Pressure Stall, Mewtwo and Rock Polish Groudon.
------------------------------------------------------------------------------------------
Scizor is an easy way of getting rid of Screens thanks to Brick Break
Dialga can also use Brick Break and become a wall breaker if he's mixed
Deoxys-E/F can set down rocks and perhaps even screens for my team
Lugia is a fast bulky wall that can take hits, weak to Groudon though
Giratina is the best physical wall, and a dandy Spin Block.
Mewtwo with a scarf is the second fastest pokemon, not to mention powerful
Darkrai fantastic Anti-Lead with Scarf or a powerful late game sweeper.
Rayquaza's Extremespeed helps greatly endgame, especially if I get rid of Giratina
Palkia is incredibly strong, with weather support, and a scarf
Celebi can Perish Song a BP pokemon if they don't catch it and Taunt
Metagross is a bulky steel type. With band he can cause trouble with meteor mash
Tyranitar He can change weather and pose a threat to the Lati@s twins
Groudon Can be a bulky supporter for my team, or a powerful sweeper thanks to Rock Polish

@ Choice Scarf
Ability: Bad Dreams
EVs: 6 HP/252 SpAtk/252 Spe
Timid nature
• Dark Void
• Spacial Rend
• Dark Pulse
• Hidden Power [FIGHTING]
---
Overview:
Darkrai is a fantastic lead, only being outsped by other Scarf users like Deoxys-A and E and he ties with himself of course. The idea is simple, I put my opponent to sleep, then switch to Kyogre. Kyogre is just there to be the muscle in the group. Nothing to serious. I was sick of using those damn sucide leads since I always found myself wishing that I could have another sweeper. I decided Stealth Rocks weren't that important and went to Darkrai. Hidden Power [FIGHTING] may seems strange to you, but Focus Blast had costed my games in the past, it really isn't a good thing.
Why not another lead:
I used Deoxys-A for some time and he did a great job at getting rocks down, and maybe getting me a kill. I did find, however, he was almost useless end game. I thought perhaps the bulk of Deoxys-E would help but he was just as useless since he didn't have the power. Darkrai helps get status and has the ability to come back late game to finish off the weakened pokemon (which is a life saver).
@ Choice Specs
Ability: Drizzle
EVs: 244 Spd/240 SAtk/24 SDef
Modest nature
• Water Spout
• Surf
• Thunder
• Ice Beam
---
Overview:
Specs Kyogre can 2HKO a 252 HP blissey with a Water Spout. Kyogre is the wall breaker of the team. Anything, besides Palkia, is taking a chuck of of their HP making it easier for my Palkia to sweep. I use surf when I'm below 60% health as Water Spout is then weaker than Surf. Ice Beam is to catch a Dragon switch in (like Rayquaza) and Thunder is for other Kyogre's or Water types.
Other wall Breakers:
Dialga is the other wall breaker in the Ubers game, I shy away from him since I rely on him to be my sleep talker and because once I use Draco Meteor I will have to switch out. On the upside he would carry Brick Break getting rid of Screens once and for all. Stopping BP mew. So Kyogre's and Dialga's roles can be switched around for personal preference.
@ Choice Scarf
Ability: Pressure
EVs: 6 HP/252 Spd/252 SAtk
Timid nature
• Spacial Rend
• Surf
• Thunder
• Aura Sphere
---
Overview: Scarf Palkia is a huge staple in the Uber metagame. Coupled with Kyogre her Surf and Thunder always hit their mark. Spacial Rend is the fast STAB move that I needed, as is Surf. Aura Sphere is mainly for coverage against steels if the clouds ain't raining. Timid is so, at worst, I tie for speed with other Palkia's.
Other sweepers:
Rayquaza- He requires set up via Swords Dance or Dragon Dance. Once that happens he can cause some trouble, with the SD set only Extreme Speed is getting off thanks to Rayquaza's very poor speed. Dragon Dance lacks the ability to OHKO a Giratina or Lugia.
Groudon- Also require set up through Rock Poilsh. He can 2HKO Lugia with Stone Edge, barring if she doesn't carry Reflect. (note that's with SR support)
(M) @ Choice Band
Ability: Sand Stream
EVs: 252 HP/38 Atk/220 SDef
Careful nature
• Pursuit
• Stone Edge
• Crunch
• Earthquake
---
Overview:
Tyranitar is my trapper and answer to the Lati@s twins. I added some extra bulk to his SpDef and made his nature careful so he can take some boosted Grass Knots and OHKO back with Crunch. Not only that he is my weather changer. Without him Rain Teams would give me hell. Also weakens Palkia's Surf along with Kyogre's. Earthquake is generally not that great move a move considering all the Flying types/Levitators. Though he hurts steels and some other pokemon.
Why not other weather:
Hail wouldn't benefit me in any way. Sand doesn't either but it gives Tyranitar a nice little SpDef boost which helps him. Groudon could help my team, but I don't need another sweeper. He could have been a Bulky-Support but that still leaves me little answer to the Lati@s twins.
@ Leftovers
Ability: Pressure
EVs: 252 HP/8 Def/248 Spd
Bold nature
• Reflect
• Whirlwind
• Roost
• Ice Beam
---
Overview:
Lugia provides screen support for my team, making it easier to switch into Groudon and Rayquaza. With Whirlwind I can get a 2HKO on Ho-Oh once the rocks are down and Roost gets rid of my rock weakness for one turn. Ice Beam is a generic move that for the only reason it hits a few of the Ubers for Super Effective damage. It's mainly a filler.
Why not another wall:
Giratina- Is a great Anti-Spin and Wall. Stopping physical sweepers thanks to W-o-W. He's weak to Dragon attacks though. Considering Dragon is a generic move to use when "you haven't got a clue" in Ubers it makes him a risky switch in. He also doesn't have an immunity to Earthquake unlike Lugia.
@ Leftovers
Ability: Pressure
EVs: 252 HP/6 Atk/252 SDef
Careful nature
• Bulk Up
• Rest
• Sleep Talk
• Outrage
---
Overview:
Dialga is a great Rest-Talker. Coupled with Bulk Up and Outrage he doesn't fear anything except Mewtwo-Palkia-Darkrai as they all carry Special Fighting moves. Since I'm trying to Max his survivabilty I maxed his HP and SpDef. Leftover is for Health regain.
Why not another Rest-Talker:
The only other common Rest talker in Uber is Kyogre, and since she's running the specs set I don't see the need to make her one and make Dialga mixed. Dialga can break screens but he's more of a Switch-In and Switch-Out kind of wall breaker, not something that can... linger around. Though, once again if you want you can reverse these two pokemons roles if you see that is the case

@ Leftovers
Ability:Technician
EV's: 248 HP / 10 Atk / 252 SpD
Adamant Nature
• Bullet Punch
• U-Turn
• Pursuit
• Roost
Overview:
Scizor is my trapper and the answer to Darkrai (most of the time). With his Bullet Punch have a total of 90 BP and Pursuit getting stronger even if the opponent doesn't switch out he leaaves all Psychics having no idea what to do. Max SpDef so he can take more hits and close to max HP for his suvivability. Roost is to heal myself on switches and U-Turn is for early game scouting,
Why not another trapper:
Tyranitar- I've tried Tyranitar on this team and he did do a fantastic job on trapping my opponent, though the weather change hurt my team more than it helped it. Scizor also has a priority move helping his low speed
@ Focus Sash
Ability: Pressure
EVs: 252 Atk/252 Spd/6 SAtk
Hasty nature
• Stealth Rock
• Superpower
• Extremespeed
• Shadow Ball
---
Overview:I picked Deoxys-F over Deoxys-E because he carries much more power. He's able to get Stealth Rock down on most games without a worry. Shadow Ball is prefered over Grass Knot so I can Combat those Deoxys-E leades easier. Extreme Speed is for picking off sashers (in the beginning) and Super Power is for Darkrai.
Against Other Leads:
Darkrai- Most Darkrai's are Scarfed and will Dark Void right off the bat, so I switch to Dialga to take the sleep then go right back to Deoxys-F. If he isn't Scarfed I can OHKO him with Super Power on the switch in back. If he is I can Stealth Rock and make the game easier.
Deoxys-E- I start off with Shadow Ball, if he taunts then I can kill him with Extreme Speed. If he gets rocks down worst case scenario I'm left with 1% and can't get my rocks down
------------------------------------------------------------------------------------------
Over View
Kyogre is one of the most powerful pokemon in the Uber game when given specs, he could severly hurt BP mew and his reciver of his passed statsSo to counter every single one of these threats I will need these things:
A powerful pokemon who doesn't mind screens/get rid of screens
A sleep talker who can take Darkrai's Dark Voids and hit back
A very fast Scarf User of my own, who is also bulky
A pokemon(s) who can hit with a fast SE or STAB attack
An extremely bulky physical wall
A way to get Stealth Rocks down with little or no cost to my team
A Steel pokemon to take the Dragon attacks running rampart.
Changing the weather once Kyogre goes down

------------------------------------------------------------------------------------------
The Roles
A powerful pokemon who doesn't mind screens/get rid of screens
Specs-Kyogre is strong enough to deal 50% or so through a screen, also giving me weather support.
A sleep talker who can take Darkrai's Dark Voids and hit back
Not many sleep talkers in Ubers, I can do either Giratina, Dialga or Kyogre. Since I'm using Ogre as a Specs wall break it's between those two.
A very fast Scarf User of my own, who is also bulky
The only thing that can take a Kyogre's Water Spout is Palkia, slap a scarf on and she's a deadly force.
A pokemon(s) who can hit with a fast SE or STAB attack
Palkia can hit with STAB Spacial Rend, she's my main sweeper, I need to keep her until End-Game
An extremely bulky physical wall
Lugia and Giratina are really the only physical walls. Giratina has W-o-W while Lugia has the bonus of not being weak to Dragon Attacks.
A way to get Stealth Rocks down with little or no cost to my team
The only two effective Stealth Rockers are: Deoxys-E and Deoxys-F. Deoxys-E can taunt Deoxys-F but Deoxys-F can hit harder than Deoxys-E.
A Steel pokemon to take the Dragon attacks running rampart.
Dialga, Metagross are really my only options in the steel area.
Changing the weather once Kyogre goes down
The three options are Groudon, Abomasnow or Tyranitar. Snow is out because hail sucks, Tyranitar can be a trapper on the Lati@s twins while Groudon can sweep with set-up.

What is left?
Groudon/Tyranitar for weather support and sweeper/trapper.Deoxys-F/E for easy SR support
Specs-Kyogre for a wall breaker and screen crusher
Lugia/Giratina for a physical wall
Dialga he can Sleep Talk and be my steel type.
Palkia/Mewtwo with a scarf I have few options
