So I have decided to make an Uber team, just my second one ever. I appreciate all kinds of criticism, but I hope you all understand the core of this team is Palkia and Kyogre, my two most explosive threats. Blissey is on just about every Uber team soo really only half of my team can possibly be completely rehauled.
Kyogre @ Choice Scarf
Ability: Drizzle
Nature: Modest (+SpA, -Atk)
EV: 4 HP / 252 SpA / 252 Spe
-Water Spout
-Hydro Pump
-Ice Beam
-Thunder
Just about the safest switches into this are Blissey, Latias, and Dialga. All of these can be handled by my team for the most part, and this sets up the rain for a Palkia sweep. Hydro Pump is for the power after I am below 63%.
Blissey @ Leftovers
Ability: Natural Cure
Nature: Calm (+SpD, -Atk)
EV: 252 Def / 40 SpA / 216 SpD
-Icy Wind
-Toxic
-Thunder
-Softboiled
Pretty standard I believe. Icy Wind allows me to Toxic Taunt Mewtwo and Safeguard Lati@s. Thunder destroys Manaphy and does good damage against Kyogre, while also possibly wrecking Palkia and Metagross.
Palkia @ Lustrous Orb
Ability: Pressure
Nature: Hasty (+Spe, -Def)
EV: 4 Atk / 252 SpA / 252 Spe
-Aqua Tail
-Surf
-Thunder
-Spacial Rend
Palkia is easily my favorite pokemon out of Pearl. Aqua Tail easily 2HKOs Blissey in the rain with the Orb, while Surf dismantles basically everything else. Spacial Rend OHKOs most dragons and Thunder abuses the rain, 2HKOing Kyogre easily. Lustrous Orb for versatility without recoil.
Metagross @ Choice Band
Ability: Clear Body
Nature: Adamant (+Atk, -SpA)
EV: 210 HP / 140 Atk / 160 SpD
-Meteor Mash
-Earthquake
-Pursuit
-Explosion
This has proven itself to be a real wall breaker. Blissey, Latias, and Lugia will usually fall to this at some point, allowing for a sweep of some sort. Pursuit catches the pink whore on the switch and also destroys Deoxys-A. Explosion is mainly for when I think his time is up.
Giratina @ Leftovers
Ability: Pressure
Nature: Impish (+Def, -SpA)
EV: 252 HP / 244 Def / 12 SpD
-Will-o-Wisp
-Rest
-Sleep Talk
-Dragon Claw
This serves as my status absorber. It also counters Metagross and Groudon with ease, among others. I chose Impish/Dragon Claw over Bold/Dragon Pulse because most Ubers have lower defense stats.
Heracross @ Choice Scarf
Ability: Guts
Nature: Adamant (+Atk, -SpA)
EV: 4 HP / 252 Atk / 252 Spe
-Megahorn
-Close Combat
-Stone Edge
-Sleep Talk
Counters Darkrai to an extent, using its Dark Void against him with Sleep Talk and Guts. Choice Scarf for some speed on this team and revenge killing.

Kyogre @ Choice Scarf
