look up. (Ferrothorn) (M) @ Leftovers
Trait: Iron Barbs
EVs: 252 HP / 168 Atk / 88 SDef
Brave Nature (+Atk, -Spd)
- Leech Seed
- Stealth Rock
- Power Whip
- Gyro Ball
Good, Maybe give Leech Seed and Leftovers since you threw those 252 HP EVs to him.

smells good (Hydreigon) (M) @ White Herb/Choice Specs
Trait: Levitate
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Flamethrower
- Dark Pulse
- Draco Meteor/Dragon Pulse
- Surf
I see you are going for a special set, so don't give it an Attack boosting nature! Switch to Timid for Speed, and invest more EVs into SAtk. If a using Draco Meteor, keep that White Herb, but for Dragon Pulse, I suggest Choice Specs.

shocker (Electivire) (M) @ Life Orb
Trait: Motor Drive
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- ThunderPunch
- Cross Chop
- Ice Punch
- Earthquake
Wild Charge and Life Orb? That's more HP loss than this guy can handle! Switch it for ThunderPunch and switch Brick Break for Cross Chop since PO makes those low accuracy moves hit a little more than they have to. Invest EVs in Atk for more power and switch nature to Jolly for more Speed.

Metagross @ Expert Belt/Muscle Band
Trait: Clear Body
EVs: 100 Def / 252 Atk / 156 SDef
Adamant Nature (+Atk, -SAtk)
- Earthquake
- Agility
- Bullet Punch
- Ice Punch
As DarthDestiny says, switch this guy with Chandelure so Zoroark ability can be used well. Give him Adamant for more attacking power, replace Meteor Mash with Agility so Metagross can outspeed, and consider Muscle Band for more attacking power.

littlefight (Zoroark) (M) @ Focus Sash
Trait: Illusion
EVs: 44 HP / 252 SAtk / 212 Spd
Timid Nature (+Spd, -Atk)
- Night Daze
- Hidden Power [Flying]
- Nasty Plot
- Flamethrower
Good set, I suggest a Focus Sash on this guy because he doesn't have the greatest defenses, and Night Daze instead of Dark Pulse to have a chance to lower opponent's accuracy.

burnbabyburn (Chandelure) (M) @ Choice Scarf
Trait: Flash Fire
EVs: 4HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Energy Ball
- Flamethrower
- Shadow Ball
- Psychic
Nothing to say here except giving him Timid instead of Modest for more Speed.
