Sharpedo @ Life Orb
Ability: Speed Boost
Nature: Adamant
EVs: 252 Attack 4 Defense 252 Speed
Moves: Waterfall, Crunch, Protect, Poison Jab
I chose to have Sharpedo on my team because it is an awesome cleaner. Speed Boost is the Ability of choice because it helps patch up Sharpedo's speed, and at +2 speed, outspending the most, if not all, of the metagame. An Adamant Nature with 252 Attack EVs and a Life Orb make sure that Sharpedo hits as hard as possible. The rest is in speed to make it faster. Waterfall hits Pokémon weak to it such as Houndoom and Rhyperoir. Crunch hits Psychic Types like Bronzong and Slowking. Protect ensures that Sharpedo will gain a speed boost. Poison Jab hits Fairy Types and Mega Abomasnow.
Flectchinder @ None
Ability: Gale Wings
Nature: Adamant
EVs: 152 Health 252 Attack 76 Defense 28 Special Defense
Moves: Acrobatics, Swords Dance, Roost, Will-O-Wisp
I chose Fletchinder to be on my team because it can break down Grass Types and can sweep if it has to. An Adamant Nature is used with 252 Attack EVs with no item are used so that Fletchinder's Acrobatics hit as hard as possible. Along with the Health EVs, the 76 EVs in Defense are used so that Scrafty cannot 2HKO Fletchinder and the 28 EVs in Special Defense help it avoid the kill from a Tangrowth Specs Leaf Storm if Fletchinder has to take Stealth Rock damage. Acrobatics is Fletchinder's strongest STAB move. Swords Dance boosts Acrobatics. Roost provides Fletchinder with reliable recovery. Will-O-Wisp cripples physical attackers.
Flygon @ Life Orb
Ability: Levitate
Nature: Timid
EVs: 4 Defense 252 Special Attack 252 Speed
Moves: Draco Meteor, Defog, U-turn, Earth Power
I chose Flygon to be on my team because I needed a hazard remover. Flygon can also help break down walls like Alomomola and Registeel. A Timid nature is used with maximum speed so that Flygon is as fast as possible. A Life Orb is used with 252 Special Attack to hit as hard as possible. Draco Meteor hits Dragon types along with Physical Walls. Defog clears away hazards. U-turn help keep momentum in my favor. Earth Power hits Steel Types like Registeel.
Rotom-Mow @ Choice Scarf
Levitate
Nature: Timid
EVs: 4 Defense 252 Special Attack 252 Speed
Moves: Thunderbolt, Leaf Storm, Volt Switch, Will-O-Wisp
I chose Rotom-C to be on my team because I wanted to be able to KO bulky Waters and revenge kill Flying resists. A Choice Scarf is used to patch up Rotom's mediocre speed. A Timid nature is used with 252 Special Attack and Speed EVs are used to hit as hard and fast as possible. Volt Switch is used to keep momentum. Leaf Storm is used to hit Ground Types who might want to interrupt a Volt Switch. Will-O-Wisp is used to hit potential switch-ins and to cripple physical attackers. Thunderbolt is for when it is better for Rotom to stay in.
Glalie @ Glalitite
Ability: (Before Mega Evolution) Inner Focus
Nature: Jolly
EVs: 252 Attack 4 Defense 252 Speed
Moves: Frustration, Ice Shard, Explosion, Earthquake
I chose Mega Glalie to be on the team because wanted a good wallbreaker. Inner Focus is the ability before Mega Evolution to avoid the flinches from Fake Outs. A Jolly Nature is used with 252 Speed EVs to make sure that Mega Glalie is as fast as possible. 252 Attack EVs are used so that It hits as hard as possible. Frustration hits bulky Grass Types. Ice Shard is used to hit weakened, faster targets. Explosion is used so that it can go out with a bang and do massive damage to any opposing Pokémon that does not resist it. Earthquake makes sure that Mega Glalie is not completely walled by Pokémon that resist Ice.
Uxie @ Colbur Berry
Ability: Levitate
Nature: Bold
EVs: 248 Health 8 Defense 60 Special Attack 192 Speed
Moves: Psyshock, Stealth Rock, U-turn, Giga Drain
I chose Uxie to be on the team because I needed a Stealth Rock setter along with an additional Hitmonlee check. With 60 Special Attack EVs, Uxie scores the OHKO Hitmonlee with Psyshock. 192 Speed EVs allows Uxie to outspeed Adamant Hitmonlee. 248 Health EVs, 8 Defense, and a Bold nature allow Uxie to take physical hits better. A Colbur Berry is used for Uxie to take Dark Type attacks better, such as Knock Off and Pursuit. Psyshock is used to hit Fighting Types such as the aforementioned Hitmonlee and Hitmontop. Stealth Rock is Stealth Rock. U-turn is used to keep momentum up and joins Rotom-C and Flygon in a Volt/Turn cycle. Giga Drain allows Uxie to hit bulky Waters and Rhyperior.
