You Got a Killer Scene There, Man!

I'm a sporadic Ubers battler and enthusiast, so I figured I'd post my newest Uber team here.

Background
  • Gen V Uber Wifi
  • Played on Simulators
  • Assume Perfect IVs unless stated otherwise.


This team is built around Arceus' "Extreme Killer" set, hence the name. I'd always considered Arceus to be completely broken and had never properly used him, so this team was made with the process in mind to use things that I hadn't used before, or to use Pokémon that I had tried before but not had much success with. Basically, I made this team to expand my knowledge on a few pokémon and the current metagame.

    Spoiler:- Making the Team:


The nitty-gritty

Lead

Thundurus (M) @ Life Orb
Trait: Prankster
EVs: 8 HP / 248 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Thunder Wave
- Thunderbolt
- Focus Blast
- Taunt

Thundurus is my lead. I chose thunderus as he can shut down most leads consistently and because he can check set up sweepers such as Dragon Dance Salamence whilst also being able to break stall and help in removing Lugia. It's basically the standard lead set. the EVs ensure minimal damage from Stealth rocks and minimal damage from Life orb Recoil whilst hitting as hard and fast as possible.

Physical Sweeper

Arceus @ Life Orb
Trait: Multitype
EVs: 252 Atk / 44 Def / 212 Spd
Adamant Nature (+Atk, -SAtk)
- Swords Dance
- ExtremeSpeed
- Shadow Claw
- Earthquake

This is the Extreme Killer set. The idea is to switch on something relatively safe, like after Scizor has used Super Power, or a Choice locked move like Pursuit, use swords dance, ??? Profit. The EVs are a little different to the standard, mine is able to outspeed base 100 Pokémon like Palkia (who can do a bit of damage to the team) and thus outspeed the Standard Arceus set. The EVs mean I take minimal damage from LO and have a little physical defence to better take whatever I may take on the switch in. I am contemplating running Fire blast over Earthquake, however I can beat reshiram and heatran much easier with Earthquake.

Special Sweeper

Mewtwo @ Leftovers
Trait: Pressure
EVs: 128 HP / 244 SAtk / 136 Spd
Timid Nature (+Spd, -Atk)
- Calm Mind
- Psystrike
- Fire Blast
- Aura Sphere

Calm Mind Mewtwo is an absolute beast. This set can take down pretty much anything it might come across. Though Victini, latios and Latias all resist the set they can not take repeated +1 Psystrikes. Should they manage to take down Mewtwo, via Draco Meteor, they then give Arceus the perfect opportunity to switch in an sweep. Mewtwo is generally brought in on things like Choice Scarfed Terrakion / any fighter, set up CM and sweep.
The Evs are tweaked to what I believe make more sense. The HP give it enough bulk to never be 2HKOd by a +1 Dragon Claw from Dialga and also mean maximum Leftover recover. The speed is tailored to outspeed ScarfTar who is the only revenge killer that I can reliably outspeed, anyway. And the rest is thrown into Special Attack.
Pretty much unstoppable in the sun.

Support / Wall

Groudon @ Leftovers
Trait: Drought
EVs: 240 HP / 16 Atk / 252 Def
Impish Nature (+Def, -SAtk)
- Stealth Rock
- Stone Edge
- Earthquake
- Dragon Tail

Groudon is my wall of choice, being able to reliably take on Rayquaza, Lucario, Zekrom and other physical attackers. His main purpose is to disrupt the weather and remove threats as quickly as possible, whilst providing Stealth Rock support to the team. I have chosen Dragon tail over Over Heat as it's more effective with getting rid of strong dragons that can cause my team trouble.
EVs = leftover number + as much bulk as possible.

Revenge Killer / Scouter / Mr Resistance

Hydreigon (M) @ Choice Scarf
Trait: Levitate
EVs: 24 Atk / 252 SAtk / 232 Spd
Naive Nature (+Spd, -SDef)
- Draco Meteor
- Fire Blast
- Dark Pulse
- U-turn

Hydreigon's main selling point on this team is all of his Key resistances to psychic, Dark and ghost which can hurt Mewtwo, Thunder aimed at Vaporeon and Water aimed at Groudon.
That being said, he is usually used to switch in on Giratina that switch in on my Mewtwo to revenge kill Mewtwo. Offencive varients get OHKOd after Rocks by Draco Meteor. That being said he's my first port of call when facing walls, as his hard hitting attacks and coverage hit pretty much every wall used in Ubers sans Blissey.
He outspeeds all base 95s with the given EVs and the rest is used for fire power. He does well at revenging Scarfed Reshiram, Spex Latis, Mewtwo, Victini and random choice locked pokemon.

Wish Support

Vaporeon (M) @ Leftovers
Trait: Water Absorb
EVs: 252 HP / 252 Def / 4 SDef
Bold Nature (+Def, -Atk)
- Scald
- Wish
- Protect
- Ice Beam

Vaporeon is my main check to things like Groudon and Kyogre. Kyogre can't touch me outside of thunder, and protect **CAN** help with that, in case of thunder, I bring in Groudon to change the weather back and dent what ever switches in next. I can also Use vaporeon to remove things like Mixmence. Scald works wonders in pretty much neutering physical attackers that could threaten my team. However, Vaporeon's main job is to just get wish passed around to my team as residual damage can build up. Plus with the team having a bulkier feel to it, it's nice to keep these guys at nice high HP so that they can better tank hits.

Closing Words
The team is still pretty fresh and not without its holes, so I came to you guys to get it rated and add improvements to it. It's currently coming off of a 7 fight win streak (well more than that, but I can't count the same guys twice ) so it does function quite well.

    Spoiler:- Feel Free to it try it yourself!:
