So I've been trying to come up with a good plan for an Uber team that still works with the Dual Screen Umbreon Sweep strategy started by Oblivian_Ty_7. Obviously it might not work as well seeing as how Umbreon is UU, but this is what I'm working with so far. I also got a bit of an idea from XtrEEmMaShEEn3k2's "Yu-Gi-Oh 5D's Yusei-themed Team." Credit for some of the descriptions goes to Smogon Strategy Pokedex and XtrEEmMaShEEn3k2's team.

Item: Lum Berry
Ability: Pressure
Nature: Jolly
252 Atk / 6 Def / 252 Spe
~ Stealth Rock
~ Spikes
~ Taunt
~ Superpower
Of all leads who can deploy entry hazards, Deoxys-S is perhaps the single best choice for your team. With its unmatched 504 Speed, getting Stealth Rock up is almost guaranteed, and if you're lucky, a few layers of Spikes. Taunt is a great choice in order to cripple Scarf Darkrai leads trying to sleep you, as you should be able to overcome the status thanks to Lum Berry and Taunt them, leaving them helpless as you deploy the entry hazard of choice. Extremespeed is the primary option.

Item: Light Clay
Ability: Pressure
Nature: Jolly
212 HP / 252 Spe / 44 Atk
~ Roost
~ Light Screen
~ Reflect
~ Whirlwind
Lugia is used in the place of Bronzong, employing pretty much the same strategy in the Umbreon Sweep team. Roost is used as an immediate healing move. Whirlwind is another move geared towards stopping physical attackers. While Lugia is sturdy enough to take as little as 67-79% from even a Choice Banded Groudon's Stone Edge, it can't keep up with a Choice Band Metagross Meteor Mash or Life Orb Rayquaza Outrage that is boosted multiple times. Therefore, it needs to remove the boosts by forcing the offending Pokémon to switch out. Reflect and Light Screen until ready to switch to Umbreon.

Item: Leftovers
Ability: Synchronize
Nature: Careful
252 HP / 252 SpDef / 6 Atk
~ Curse
~ Payback
~ Wish
~ Protect
Same as with the OU Umbreon Sweep Team. Under the protection of the screens, Umbreon is able to come in and reak havoc like only us Umbreon lovers, well love :P

Item: Leftovers
Ability: Pressure
Nature: Bold
248 HP / 248 Def / 12 SpD
~ Will-O-Wisp
~ Rest
~ Sleep Talk
~ Dragon Pulse
Giratina is the physical wall of the team. Giratina’s physical walling ability is enhanced by its ability to Will-O-Wisp, effectively cutting the opponent’s Attack into pieces. Sleep Talk enables Giratina to absorb status, and Dragon Pulse enables Giratina to severely damage other Dragon-types, OHKO Deoxys-A, and deal a respectable amount of damage to Ho-oh and Darkrai, Groudon. Dragon Pulse has a slight chance of 3HKOing an opposing Giratina, and will always break Groudon's Substitutes in case one tries to Substitute to block Will-O-Wisp.

Item: Leftovers
Ability: Natural Cure
Nature: Calm
252 Def / 40 SpA / 216 SpD
~ Aromatherapy
~ Ice Beam
~ Thunder Wave
~ Softboiled
With Blissey, switch in on a special attacker, relieve the team of any status ailments, and switch back out in the face of the physical threat which will likely replace the harmless special attacker. I'd most likely switch to either Giratina or Rayquaza after using Blissey, or back to Lugia if it is still up so I can Dual Screen again.

Item: Life Orb
Ability: Air Lock
Nature: Adamant
4 HP/252 Atk/252 Spd
~ Swords Dance
~ Dragon Claw
~ Extremespeed
~ Flamethrower
Rayquaza is more of a backup than anything. It's also the only safe switch I have against Water Spout Kyogre leads, since Rayquaza resists Water Spout and Air Lock negates the Rain boost. It can also set up fairly safely behind Dual Screens.
Basically, start off with Deoxys setting his Spikes and Stealth Rock. When it comes time for Lugia to come in, he can first Whirlwind away any Pokemon that might make it hard to set up the Dual Screens, or just wait and switch in when a better opponent Pokemon is in. When the screens are set up, switch to Umbreon. After Umbreon has reaked havoc, we can go to Giratina or Rayquaza, depending on the situation. Anywhere in the battle, Blissey can come in the heal the team of any status ailments.
