A Little Old, a Little New, but Mostly Inbetween

[Duo]

Overview:

Breakdown:

Deoxys-A @ Focus Sash
Ability: Pressure
EVs: 4 Atk / 252 SpA / 252 Spe
Hasty/Naive Nature (+Spe, -Def/SpD)
- Ice Beam
- Shadow Ball
- Stealth Rock
- Superpower

Deoxys is my lead. Lay down Stealth Rock and survive with Focus Sash, then attempt to sweep with its superior speed.

Gengar @ Focus Sash
Ability: Levitate
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature (+Spe, -Atk)
- Focus Blast
- Icy Wind
- Shadow Ball
- Thunder

Gengar is a revenge killer, plain and simple. He's here to take out Rayquaza (Icy Wind will OHKO it 100% of the time Stealth Rock is down) and Tyranitar (Focus Blast) specifically, but he's also a good match against Chansey/Blissey (Focus Blast), as well as a multitude of others.

Latias @ Leftovers / Soul Dew
Ability: Levitate
EVs: 252 HP / 4 Def / 252 Spe or 112 HP / 204 SpA / 192 Spe
Timid Nature (+Spe, -Atk)
- Dragon Pulse
- Protect
- Roar / Thunder / Calm Mind
- Wish

Latias is my squad's support. I don't have Chansey or Blissey, so it's useful to have her able to use Wish on my team. If Soul Dew makes its way into BW, then I'd be happy to put Thunder or Calm Mind on her (which though, I am uncertain); in the meantime though, she shall be utilising Roar.

Kyogre @ Choice Specs
Ability: Drizzle
EVs: 252 HP / 252 SpA / 4 Spe
Modest Nature (+SpA, -Atk)
- Hydro Pump
- Ice Beam
- Thunder
- Water Spout

'Nuff said.

Dialga @ Choice Scarf
Ability: Pressure
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature (+Spe, -Atk)
- Draco Meteor
- Dragon Pulse
- Fire Blast
- Thunder

Dialga's part revenge killer, part special sweeper. He does both roles very well, and is a great support for Deoxys.

Garchomp @ Choice Band
Ability: Sand Veil
EVs: 4 HP / 252 Atk / 252 Spe
Adamant/Jolly Nature (+Atk/+Spe, -SpA)
- Dragon Claw
- Earthquake
- Stone Edge
- Outrage

Not wanting to only have one non-legendary on my team, Garchomp rounds up the bunch. Acting as my team's physical sweeper, he'll be able to get through at least one opponent.

Mewtwo craps allove ryor gengar out him in instead.
Latias idk ignore doesn't seem to be a Hoosiers to have a wall weak to types practically everything carries does it? Draco, ice beam, shadow ball that every1 has 4 psychics its kind of the wrong environment 4 latias
Kyogre: IMO scarf if you have water spout
Deoxys:SHADOW BALL NOT SIGNAL BEAM ITIS BTEER IN EVERY SITUATION. And maybe extremespeed.
Dialga-replace with palkia
Palkia@choice scarf
-hydro pump/surf
-aura sphere/earth power/other special attacking move
-Draco métier/spacial rend
-thunder

-With Gengar, if you're going to be using the incredibly gimmicky Icy Wind, at least run a Focus Sash. You're not going to need to slow down things that are already slower than Gengar, and they will all kill you in one hit. And how is it taking Rayquaza? Almost all of them are DD sets, and if it gets one up, what's it gonna do?
-Latias without Soul Dew, which is only usable in DW Ubers, isn't really fit for Ubers. Replace it with Lugia:
Great Wall @ Leftovers
Impish
252 HP/ 176 Def/ 80 Sp. Def
-Roost
-Reflect/ Substitute
-Dragon Tail/ Ice Beam
-Toxic/ Whirlwind/ Earthquake

-Regirock really doesn't know what he's talking about with Kyogre, its fine as is, although testing a Timid nature won't be a bad idea, allowing you to tie with other Kyogre's and the like
-If Deo-A is your lead, can't you place it on top for convenience sake?
-Again, Regirock is off with Scarf Dialga, its a great set.
-Yeaa... Don't use Haxorus though. Garchomp is more fit for Ubers, or Rayquaza, just not him.

I agree that Haxorus belongs in OU. Garchomp does a much better job in Ubers. How about you consider the classic Scarfchomp set?

Garchomp@ Choice Scarf
4HP/252Atk/252Spe
Nature: Jolly

Ability: Sand Veil

Outrage
Earthquake
Dragon Claw
Stone Edge

Deoxys needs exteme speed against other Deoxys or any other lead with priority. Some popular scarf users (even modest base 90s like Kyogore) outspeed Deoxys-A, so I can't see him ever sweeping or doing much more than getting down stealth rocks and fainting. Without a fire attack, random Forretress leads lay down hazards, rapid spin to break the sash and blow away your rocks, then finish Deoxys off with gyro ball.
With the new wish mechanics, Latias's wish is very underwhelming and won't pass much Hp on to a teammate by uber standards. I see this thing wishing and dying. Scarf Kyogore and Palkia rape your Latias (without soul dew) with their superior speed, and those are pokemon that Latias is supposed to counter when it does have soul dew. Soul dew is only for use in dream world, where this team would get raped hard by all of the superior items and abilities available in that tier. Latias is dead weight without soul dew.
Gengars sash is liable to be broken easily by stealth rock, and I just see it as adding more fragility to an already defensively fragile team. Gengars focus blast does laughable damage to Chansey/Blissey, and it isn't revenge killing much with its low speed and lack of a scarf. Gengar doesn't do much damage either by uber standards. It is useable in the right team, but never the strongest choice in my opinion, and it looks to be dead weight on this team.
Nothing on your team has priority or outspeeds a scarfed base 90. Dragon dance Rayquaza has a field day after one boost.
Replace Gengar and Latias, and maybe Deoxys too, at least give Deoxys extreme speed. You could also take out Garchomp, because it is a 3rd choiced pokemon, and your team can't switch effectively. Garchomp needs to have choice scarf to give your team much needed speed, or be replaced too. Ferrothorn is one of the best non-ubers to use, and it gives your team a much needed way to counter Kyogore.
If you truly want to persist with Latias, then use a dual screens variant with light clay to set up for a powerful sweeper like a DD Ray or a extreme killer Arceus.
