I am gonna do my best to answer this RMT.

I recommend this set instead of your Luxray set. Intimidate is not the best option for him since his Defenses are not that bad. Guts is better option here.
Luxray (M) @ Flame Orb
Trait: Guts
EVs: 128 HP/ 252 Atk/ 64 Def/ 64 SDef
Adamant Nature (+Atk, -SAtk)
- Wild Charge
- Facade
- Ice Fang
- Crunch
This set takes advantage of Luxray's great Attack stat and his Ability, Guts. With Flame Orb, Guts activates, boosting Luxray's already high Attack stat. Wild Charge is STAB and Facade is cool with Guts and the Flame Orb. Though this combo suits Swellow better because he gets STAB from Facade. Ice Fang is coverage against Ground types. Crunch is good paired with his high Attack stat.

Ok, Gardevoir is not the best Psychic type in NU. And anyways, don't run Trace on him. Go with Synchronize. Mr.Mime is better suited for your team. Here is a moveset for him:
Mr. Mime (M) @ Life Orb
Trait: Technician
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Icy Wind
- Charge Beam
- Psychic/ Psyshock
- Nasty Plot
Nasty Plot + Technician sweeper. Smogon says that it's inferior to their other sets. But that's not really true. The Technician set works wonders. Nasty Plot is for boosting his Special Attack and Icy Wind hits a lot of Pokemon for super-effective damage in NU and is boosted by Technician and has a chance to lower the foe's Speed. Charge Beam is also boosted by Technician and can raise Mr.Mime's Special Attack. With Nasty Plot, that boost can make him a dangerous sweeper. Psychic is STAB but Psyshock can hit those annoying walls and is STAB as well.

Ok, there are a lot of stuff to fix on that Haunter. Why giving Eviolite to Haunter? Even with that Item, his Defenses will be paper-thin. Change his Item to Life Orb. Also, your EVs are weird. Even if he has Eviolite and maxed out 252 Special Defense EVs, his Defenses will be low. Give him a EV Spread of 252 SAtk/ 252 Spd/ 4 HP. Switch Thunderbolt for HP Ground and switch Destiny Bond for Substitute. This Haunter will be a dangerous sweeper.

If you want a Physical Fire type, i wouldn't recommend Rapidash. The best out there is Emboar who has two fantastic STABs. I recommend this set for him.
Emboar @ Choice Band
Trait: Blaze
EVs: 252 Atk/ 212 HP/ 44 Spd
Adamant Nature (+Atk,-SAtk)
- Flare Blitz
- Superpower
- Wild Charge
- Earthquake
This guy is like a mini-Darmanitan. With Choice Band, he hits really hard. Can't wait for Reckless.... Flare Blitz is STAB and Superpower is STAB and is for those who resist Flare Blitz. Wild Charge is for the bulky Water type such as Alomomola. Earthquake is for covering as much types as possible.

Ok, Golurk is not the best abuser of No Guard so i recommend Iron Fist with a set that abuses that Ability.
Golurk @ Choice Band
Trait: Iron Fist
EVs: 252 Atk/ 252 Spe/ 4 HP
Adamant Nature (+Atk,-SAtk)
- Shadow Punch
- Earthquake
- Fire Punch
- ThunderPunch
Shadow Punch is STAB and boosted by Iron Fist. Earthquake is STAB. I've always considered Stone Edge but Fire Punch and ThunderPunch cover everything that Stone Edge covers but in better because they are boosted by Iron Fist.

Switch his EVs to 252 SAtk/ 252 Spd/ 4 HP. Replace Scald for Surf for more power and replace Confuse Ray for HP Electric. All you want to do with Gorebyss is to sweep. Confuse Ray is not part of that plan. You could run Baton Pass on him but Shell Smash + Baton Pass combo is banned. Also, switch Leftovers for White Herb for nullifying the Defense losses.
