Jirachi @ Lum Berry
Serene Grace
252 Atk | 176 Spd | 80 HP
Jolly [+Spd, -Sp.Atk]
U-Turn | Thunder Wave | Iron Head | Stealth Rock
Lead Jirachi can safely set up stealth rock against most other leads this meta game and is mainly used as an annoyer and taking advantage of its flinch rate with serene grace and iron head. with t-wave paralyzing them then going for a flinch gets them pretty well stuck and gives me an upper hand.
Weak to: Fire 2x, Ground 2x
Resistant to: Normal, Flying, Rock, Steel, Grass, Psychic, Ice, Dragon
Immune to: Poison 0x

Salamance @ Leftovers
Intimidate
252 HP | 180 Def | 76 Spd
Jolly [+Spd, -Sp.Atk]
Roost | Earthquake | Dragon Claw | Dragon Dance
With Salamence's overlooked DEF I can say that he has an easy time setting up Dragon Dance on opponents such as Lucario and can heal off any damage with Roost keeping him alive that much longer, earthquake being great coverage and dragon claw for STAB, this set really helps this team IMO.
Weak to: Ice 4x, Dragon 2x, Rock 2x
Resistant to: Fighting, Bug, Fire, Water, Grass
Immune to: Ground 0x

Starmie @ Life Orb
Natural Cure
252 Sp.Atk | 252 Spd | 4 HP
Timid [+Spd, -Atk]
Rapid Spin | Thunderbolt | Ice Beam | Hydro Pump
My rapin spinner to stop stealth rock set ups against my team, also has great coverage between hydro pump, thunderbolt, and ice beam. it stops some threats such as scizor from switching in and walling my latias and also takes care of salamence with ice beam.
Weak to: Bug 2x, Ghost 2x, Grass 2x, Electric 2x, Dark 2x
Resistant to: Fighting, Steel, Fire, Water, Psychic, Ice

Gyarados @ Leftovers
Intimidate
252 Atk | 252 Spd | 4 Def
Jolly [+Spd, -Sp.Atk]
Waterfall | Dragon Dance | Taunt | Earthquake
One of my late game sweepers, can safely set up Dragon Dance a lot of the time, waterfall for STAB and great type coverage paired with Earthquake, it being great coverage as well, while being able to Taunt my opponent is also a plus as well.
Weak to: Rock 2x, Electric 4x
Resistant to: Fighting, Bug, Steel, Fire, Water
Immune to: Ground 0x

Lucario @ Life Orb
Inner Focus
252 Atk | 252 Spd | 4 HP
Adamant [+Atk, -Sp.Atk]
Swords Dance | Extremespeed | Close Combat | Stone Edge
Lucario helps cover some of my weakness such as dark / ghost to bring in latias more safely and prevent it from getting walled by scizor/pursuitlax. lucario also gives me an answer to gyarados with stone edge.
Weak to: Fighting 2x, Ground 2x, Fire 2x
Resistant to: Normal, Rock, Bug, Ghost, Steel, Grass, Ice, Dragon, Dark
Immune to: Poison 0x

Latias @ Choice Scarf
Levitate
252 Sp.Atk | 252 Spd | 4 HP
Timid [+Spd, -Atk]
Trick | Thunderbolt | Surf | Dragon Pulse
Having a tricker on the team is important IMO, it allows my pokemon who setup to do this much easier, while thunderbolt and Dragon pulse have great pairing and can rid of some threats for this team. I really enjoy this pokemon here on this team, i've only considered changing choice scarf to choice specs though, not sure on this yet though.
Weak to: Bug 2x, Ghost 2x, Ice 2x, Dragon 2x, Dark 2x
