This is my team based on a Gyarados sweep with many back up sweepers if something like Vaporeon won't die and Protects on my Bounces.
I'd like to thank zerowing for inventing pokemon.
At a Glance:







Naive 252SpA / 252Spe / 4HP
~Fire Blast
~Earth Power
~Stealth Rock
~Explosion
It gets up Rocks, and just stays around to be a pain. Explosion got a OHKO on some Blissey that I encountered. He is here to hit hard and provide resistances that my team relies on so much. Against Jirachi and Hippowdon I Fire Blast right off the bat. Versus Ninjask and Bronzong I Stealth Rock, and finally on Metagross I use Earth power.

Adamant 72HP / 252Atk / 184Spe or 60HP / 252Atk / 196Spe
~Dragon Dance
~Bounce
~Waterfall
~Stone Edge
Best Gyarados set ever (Screw DD LO). I came up with the idea when Katherine swept me using Bounce :( . I kind of stole matty's set, but the EVs are a coincidence. Bounce for Water resists and Stone edge is for other Gyarados, Salamence, and Zapdos. 184Spe is to get the jump on Starmie, Raikou, and Azelf.

Modest 232 HP / 240 SpA / 36 Spe
~Leaf Storm
~Thunder Wave
~Hidden Power Fire
~Recover
Leaf Storm is for hard hitting STAB that helps with Rain teams (Gyarados eats Ludicolo). Hidden Power Fire is for that OHKO on those Scizors thinking they can come in and U-turn stuff. Recover over Rest becauses when Celebi is out it wants to get as many hits as possible. Here to take out Bulky waters like Vaporeon that ruin a Gyarados sweep.

Adamant 252HP / 220Atk / 12Def / 24Spe
~Meteor Mash
~Pursuit
~Explosion
~Earthquake
Powerful, but fragile, and Forretress is a problem. The purpose of it is to take out Blissey for Latias and Heatran, and Explode shortly after, taking a big chunk out of everything. The EVs allow Metagross to outspeed most Skarmory and Explode. The frailness makes this not-very-appealing but the resistance to Dragon is needed. I may go back to using IggyBot's Scizor set.

Adamant 252Atk 80SpA 176Spe
~Outrage
~Earthquake
~Fire Blast
~U-turn
Comes out and gets a free switch into Rotom-A and Zapdos and tears stuff up.
Outrage has 60% chance to 2HKO Max/Max Suicune after Stealth Rock. It really used to suck but now its a great Pokemon. Here for resists and sweeping.

Naive 252Atk / 60SpA / 196Spe
~Stone Edge
~Close combat
~Overheat
~U-turn
It is proving useful, I love it if someone is stupid enough to let Blissey stay in. I use Stone Edge over Mach Punch to deal with Flying-types, and Lucario isn't getting past Gyarados any time soon. U-turn for scouting. It is just here for a mid-game sweep, scout, or revenge kill.
I hope the descriptions are enough. Otherwise Rate/hate/steal.
Testing/Retired Members

Bold 252HP / 216Def / 40SpA
~Discharge
~Toxic
~Ice beam
~Recover
Porygon2 was suggested to replace Latias (Now Celebi), although it doesn't really go with the Offensive feel of the team

Jolly 252HP / 40Atk / 216Spe
~Earthquake
~Stone Edge
~Roost
~Swords Dance
I found this in the old think tank thread, and my choice was this or Flygon for those resists. It was made by Legacy Raider, although I must be using it wrong, it doesn't fit well with the team. If you are going to suggest Flygon please don't bother with Choice Scarf, I dislike the lack of power. Swords Dance for set-up, Earthquake for STAB, and Stone Edge for coverage. Replaced by Flygon.

Modest 160HP / 252SpA / 96Spe
~Draco Meteor
~Surf
~Dragon pulse / Psycho Shift
~Roost
I miss my speed but the only reason it is on here is to take out Bulky waters. Latias is kind of a weak link, not doing enough to OHKO Swampert get the 2HKO on Suicune if it switches in on the Calm mind, or 2HKO Vaporeon. I need another immunity or resistance to Ground if I am going to replace it, maybe with Celebi. I will probably start testing Psycho Shift if Blissey keeps popping up. August invented this set. Replaced by Celebi.
