Uber RMT - PLEASE comment (did that sound too desperate?)
This is an Uber team that I have been using for the last couple weeks (on a simulator called "Pokemon Online", in which Arceus is not banned in case you were wondering how I tested this. However, you can't get higher than 100 EV's in each stat) No pokemon on the team are weak to dragon-type moves. I've won ~50% of battles with it. I'm new to Ubers, still, and I would really appreciate help on improving this team.

Scarf Kyogre is my lead and revenge killer. Not much to be said here, and most people know how it works since it's on >50% of Uber teams as of June. I changed one thing from the standard scarf set; I changed its nature to Modest to hit with more power. I know I'm going to be advised to change to timid, but I like using Modest nature and that's why I put it there. I'm not concerned about outrunning everything because I have a POWERFUL priority move coming from Scizor, also on my team. Scarf Kyogre (as opposed to specs Kyogre) also aids Dialga by luring out Blissey and Giratina, both of which Dialga can easily set up on.

# Adamant
EV's: 200 HP/56 Atk/252 SpD
~Bullet Punch
~Pursuit
~Superpower
~U-Turn
I put Scizor on this team mainly for its powerful priority move, Bullet Punch. It picks of foes who were weakened by Kyogre or Dialga and can revenge kill Deoxys-a and Darkrai. With its defensive EV spread and the extreme commonality of dragon-type attacks in Ubers, Scizor can really take a hit. He also greatly appreciates the wish support from Blissey.

This set is AMAZING. It takes special attacks very well with its EV's and perfect typing. When I use this at the right times, I can severely damage the opponent's team. This set's three biggest threats are Groudon, Lugia, and Skarmory. I haven't seen a Skarmory in Ubers yet, but if I were to I could easily switch in Kyogre and take care of it. Lugia is countered by Blissey and Kyogre and Groudon is countered by Arceus and Lugia (normally I'll switch in Arceus though for fear of Rock Polish) You're probably thinking that implementing Toxic Spikes (and also SR for Scizor and Kyogre) on this team would be a good idea. But in order to do that I'd pretty much have to waste a spot for Forre (who I hate using since he's easily set up on) and switch a pokemon for Giratina to spin block, which I don't want to do. Also, this set counters Darkrai without Focus Blast pretty well (even if it does have focus blast it can still absorb sleep and switch to Blissey)
Blissey@Leftovers

# Calm
EV's: 252 Def/252 SpD/4 Spe
~Wish
~Protect
~Seismic Toss
~Toxic
We all know how Blissey works. I added Blissey because I needed a counter to CM Mewtwo with Aura Sphere, Lati@s, and wish support, mainly for Scizor, Kyogre, and the other 3 on occasion.
Lugia@Leftovers
! Pressure
# Timid
EV's: 252 HP/64 Def/192 Spe
~Reflect
~Ice Beam
~Roost
~Whirlwind
Lugia is on my team to PHaze and come in on Fighting and Ground-type attacks aimed at Dialga and Blissey. He is my counter to Scizor, SD Arceus, and Garchomp.

# Timid
EV's: 100 HP/8 Atk/100 Def/100 SpA/100 SpD/100 Spe
~Judgment
~Recover
~Psych Up
~Ice Beam
First, let me say something about the nature and EV's. Since everything is capped at 100, I am forced to use Timid nature in order to outrun a Specs Kyogre that's Timid and has 252 EV's in Speed. However, if this were not the case, my nature and EV spread would be this: #Calm, 232 HP/80 Def/72 SpD/124 Spe.
Arrceus is essential to this team and counters many threats that could otherwise lose me the battle. Namely, Specs Kyogre, Rock Polish Groudon, and CM Manaphy in the rain. I originally had CM instead of Psych Up, but I changed it because it works better in countering Manaphy (who, by the way it always outruns by 3 points) and has an added bonus of gaining speed from Groudon and can defeat other CM users in a pinch.
Thanks to all of you who read and help with my team!
