Garchomp:
Ability: Rough Skin
EVs: 240 HP / Def Atk / 92 Spe
Nature: Impish
Item: Rocky Helmet
- Earthquake
- Dragon Tail
- Fire Blast
- Stealth Rock
This Garchomp should usually be the lead of the team for setting the Stealth Rock. Earthquake is it’s main STAB and hits almost everything hard.
Dragon Tail phases foes and racks up entry hazard damage.
Fire Blast roasts Steel types that resist Earthquake like Skarmory, Mega-Scizor and Ferrothorn.
Stealth Rock is one of the best moves in the game, if not the best, I believe it's Mandatory a team having one Stealth Rock setter
Gyrados
Ability: Moxie
Nature: Jolly
Evs: 88 HP / 220 Atk / 24 Def / 176 Spe
Item: Flyinium Z
- Waterfall
- Bounce
- Earthquake
- Dragon Dance
Waterfall is Gyrados main STAB and hits pretty much anything, except for Grass Pokémon, which can be put down by Supersonic Skystrike, a terrific STAB that can put some other bulky Pokémon down. Earthquake hits Toxapex and steel types with a nice extra damage. Dragon Dance can be used to buff Gyrados and can be used both early and late in game. Moxie gives a nice attack boost for every KO, which can make Gyradors terrifying to it’s opponents.
Mega-Scizor:
Abilty: Technician
Nature: Adamant
Evs: 248 HP / 16 Atk / 60 Def / 124 SpD / 60 Spe
Item: Scizorite
- Bullet Punch
- Bug Bite
- Swords Dance
- Roost
A very bulky Pokémon with a reliable recovery, Roost is mandatory for Scizor. Bullet Punch is the best priority in OU , that gets bonus for STAB and Technician. Bug Bite also receives a bonus for Technician and hits Slowbro, Tangrowth and water types that resist Bullet Punch.

Thunderbolt is Zapdos main STAB, hitting decently hard.
HP Ice is Landorus Garchomp, Dragonite and Gliscor.
Roost is a reliable recovery.
Defog is used for removing hazards and is specially useful for the Pokémon below.
Volcarona:
Ability: Flame Body
Nature: Timid
Evs: 252 SpA / 4 SpD / 252 Spe
Item: Lum Berry
- Fiery Dance
- Bug Buzz
- Giga Drain
- Qiver Dance
Usually people use Fire Blast, but Fiery Dance has a 50% chance of raising Volcarona Sp Atk, which is great and has saved my ass quite a few times in 6th gen. Bug Buzz has a good neutral coverage and deals heavy damage. Giga Drain is useful for water type Pokémon. Quiver Dance puts Volcarona at a Great speed tier and gives it power to sweep through teams.
Magearna:
Ability: Soul-Heart
Nature: Modest
Evs: 252 HP / 252 SpA / 4 SpD
Item: Choice Specs
- Fleur Cannon
- Flash Cannon
- HP Fire
- Volt Switch
Fleur Cannon is Magearna main STAB, with incredible 130 Base Power; it’s side effect is helped by Soul-Heart. Flash Cannon is a very reliable STAB, since it can use it over and over and abuse Soul-Heart boosts. HP Fire serves for Scizor, Genscect and can OHKO Ferrothorn. Volt Swith makes Magearna serve as a Pivot
