My last team I wasn't exactly satisfied with, as it failed to stop some of the biggest threats due to some lacking resistances. That, and being Scizor-weak.
Changes from the last team to this one is the replacement of Bronzong with Heatran, along with Latias for Jirachi. More will be explained later.
Heatran @ Shuca Berry
Ability: Flash Fire
Nature: Timid (-Atk, + Spe)
EVs: 4 HP / 252 SpA / 252 Spe
~Stealth Rock
~Fire Blast
~Earth Power
~Explosion
Lead Heatran set, copied directly off the DPPt Analysis. He has more speed than Bronzong, Not to mention LeadTran here gets the job done just as well, and he has a Fire immunity. I also plan to use this Pokemon to sweep, another advantage over my previous team. Overall, he's a bigger threat to the likes of Scizor, who basically spelled death on my other team.
Gyarados @ Wacan Berry
Ability: Intimidate
Nature: Adamant (-SpA, + Atk)
EVs: 156 HP / 108 Atk / 100 Def / 144 Spe
~Dragon Dance
~Waterfall
~Stone Edge
~Taunt
Gyarados, but not the offensive type needed for late game sweeping. Rather, I wanted a more defensive EV spread on this Gyarados to make sure it gets in a Dragon Dance or two. Another redeeming feature is the fact that this Gyarados can be used in any part of the game, which in my case is a plus. I wanted a Wacan berry to make sure I get TWO Dragon Dances in case of a Switch + Electric Attack that doesn't involved Choice Specs/Band.
Scizor @ Life Orb
Ability: Technician
Nature: Adamant (-SpA, +Atk)
EVs: 32 HP / 252 Atk / 224 Spe
~Swords Dance
~Bullet Punch
~Brick Break
~X-Scissor
SD Scizor, and he didn't go through any changes except for X-Scissor replacing Roost. For one thing, I have a WishPasser that can hopefully help restore health. More importantly, X-Scissor is a great way to beat up Bulky Waters, which propose a problem to Heatran and to a lesser extent, Flygon. Brick Break over Superpower because I don't appreciate the whole Atk and Def down factor. This my main Physical Sweeper.

Jirachi @ Leftovers
Ability: Serene Grace
Nature: Impish (-SpA, +Def)
EVs: 240 HP / 56 Atk / 76 Def / 136 Spe
~Wish
~Zen Headbutt
~U-Turn
~Reflect
This is my support, with setting up Wish and Reflect before U-Turning when appropriate. I chose Reflect, since most of my offensive counters to my Pokemon are on the physical attacking spectrum.

Gengar @ Choice Specs
Ability: Levitate
Nature: Timid (-Atk, +Spe)
EVs: 4 HP / 252 SpA / 252 Spe
~Shadow Ball
~Thunderbolt
~HP Ice
~Trick
SpecsGar meant to Sweep, while it comes in on the likes of a Fighting/Ground/Normal move. I did not choose to use Focus Blast, since I do not have any BoltBeamers on my team or anyone else with that kind of coverage. The accuracy puts me off too. 538 or so Special Attack is a good thing, and I feel that something that powerful will be able to greatly help my team.

Flygon @ Choice Scarf
Ability: Levitate
Nature: Adamant (-SpA, +Atk)
EVs: 80 HP / 252 Atk / 176 Spe
~Earthquake
~Outrage
~Stone Edge
~U-Turn
Revenge kill, and he's the one that has the most pressure when it comes to battling. Stone Edge is to take out the likes of Zapdos and Gyarados, the latter being able to counter quite a few of my teammates. He's also here for the sake of an electric resist, or more precisely, immunity, which is what my team needs. This guy will be my scout for counters, which is what I always like to do with U-Turn.
