Swampert @ Leftovers
Relaxed Nature
Ev's 240 HP/ 216 Def/ 52 Spa
Moveset
-Roar
-Icebeam
-Earthquake
-Stealh rock
I use swampert as my lead because of his resistance to electricity which can be problematic, and though he is weak to a grass knot or hidden power grass his main use is being able to easily take care of popular leads such as aerodactyl and being able to set up a SR with ease.

Jolteon @ CHoice Specs
Timid Nature
Ev's: 4 HP/ 252 SpA/ 252 Spe
Moveset
-thunderbolt
-Baton Pass
-Shadow Ball
-Hidden Power Grass
Jolteon makes for an amazing sweeper in the right situation with his extremely high SpA after choice specs, and his incredibly high speed. His thunderbolt can easily OHKO skarm and other threats, HP grass for swampert, and shadowball for those pesky psychic/ghost types, as well as Baton Pass for seemlessly switching into counters and being able to scout.

Scizor @ Choice Band
Adamant Nature
Ev's: 32 HP/ 252 ATk/ 224 Spe
Moveset-
-U-turn
-Pursuit
-Superpower
-Bullet Punch
Scizor makes for my high Atker. Sporting U-turn for an easy high amount of damage and a switch to a possibly better type, pursuit for any fleeing psychics, superpower for dark/wall types like blissey, and the ability to OHKO heatran/magnezone, even though it drops ATK, and bullet punch for gengar/or even salamence.

Heatran @ Choice Scarf
Naive Nature
Ev's:4 Hp/ 252 SpA/252 Spe
Moveset
-Fire Blast
-Earth Power
-HP ice
-Explosion
I eliminated cressalia for a special wall became all that apparent that it wasn't as much needed as a good quick counter was, Heatran can deal with many counters in the game with an extremely high STAB fire blast for scizors, HP ice will scare of a salamance(this included considering jolteon is already packing HP grass for water types) and explosion in case of emergencies, with earth power for other heatrans/fire types

Gyrados @ Leftovers
Adamant Nature
Ev's: 4 Hp/ 252 Atk/ 252 Spe
Moveset
-Taunt
-Stone Edge
-Waterfall
-Dragon Dance
Gyrados made a better place in my team than my DD mence, being able to easily switch in on a blissey switch, taunt it, and get a free DD off to run straight through many teams with his extremely high ATK with waterfall and a counter for other gyrados/DD mences with Stone edge.

Vaporeon @ Leftovers
Bold Nature
Ev's: 188 HP/ 252 Def/ 68 Spa
Moveset
-Wish
-Toxic
-Surf
-Protect
Wish-Protect is a nasty combo, with Water absorb he's an easy gyrados counter with toxic and protect to keep him alive, and with Surf for STAB damage and provide team wish support as well.
So this is my first team, comments?
