My NU Team that i use for my Part-Time Gym Leader job.

Lapras @ Leftovers
Trait: Water Absorb
EVs: 252 HP/ 252 Atk/ 4 SDef
Adamant Nature (+Atk,-SAtk)
- Dragon Dance
- Drill Run
- Waterfall
- Ice Shard
I had Mantyke before as my lead. Kicked him out for Gorebyss. Awesome lead with Shell Smash until i decided to ban Shell Smash in my Gym. Lapras comes to the rescue! I always start with D-Dance unless i am sure that my alternate move KO'es the foe. I usually have time to do one D-Dance. Anyways, i try to do as much as possible, maybe 3 or 4. Drill Run covers his Electric and Rock weaknesses. Waterfall is powerful STAB and also covers his Rock type weakness and Ice Shard has this nice Priority thingy and can hit very hard boosted with D-Dance.

Slaking @ Choice Band
Trait: Truant
EVs: 252 Atk/ 252 Spe/ 4 HP
Adamant Nature (+Atk,-SAtk)
- Return
- Earthquake
- Night Slash
- Retaliate
My revenge killer. Extremely powerful but his ability kills him. Without his ability, he would be Ubers. Return is STAB and hits hard with Choice Band and Adamant Nature. Earthquake is for hitting as much types as possible and Night Slash is for those Ghosties or those Levitating Pokemon and has a high Critical hit ratio. Retaliate is for when you put Slaking after your ally dies. It is STAB and more powerful than Return in certain circumstances.

Fraxure @ Eviolite
Trait: Mold Breaker
EVs: 252 Atk/ 252 Spd/ 4 Def
Jolly Nature (+Spd,-SAtk)
- Dragon Dance
- Swords Dance
- Outrage
- X-Scissor
I had Magmortar in this spot before. The core of my team, he would literally smash entire teams until Smogon placed him in RU. I then took Lampent and it went horribly. I went for a Stalling Flareon and i just didn't like his performance. I gave up on my Fire type search and i went for someone who could crush teams as well as Magmortar. I went with Zweilous and everything went well except for the fact that Hustle was really infuriating as i would miss in the important moments. So i went with Fraxure and here, i am running a Double Dance set. Dragon Dance for boosting up his Speed a bit and Swords Dance spices up his Attack. Outrage is STAB and puacks a punch and X-Scissor is covers a lot of stuff in NU like Absol and Exeguttor.

Rotom-S @ Choice Scarf
Trait: Levitate
EVs: 252 SAtk/ 252 Spd/ 4 SDef
Timid Nature (+Spd,-Atk)
- Thunderbolt
- Volt Switch
- Air Slash
- Trick
I had Mr Mime in this place before to combat Fighting types. He did it pretty well but he was way too frail. I turned to Musharna and went for a Calm Mind set but it worked out horribly. I went for a different approach to vanquish Fighting types and i thought of Flying types. Braviary is a very powerful Flying type but he carried that Fighting type weakness. I came up with Rotom-S when i saw the outstanding performances he was giving to Jonachin. Thunderbolt is STAB and hits hard and Volt Switch is for switching out safely while doing some STAB damage. Air Slash is STAB as well and that flinch chance is really useful. Trick is to screqw up walls such as Alomomola and Lickilicky.

Golurk @ Choice Band
Trait: Iron Fist
EVs: 252 Atk/ 252 Spe/ 4 HP
Adamant Nature (+Atk,-SAtk)
- Shadow Punch
- Earthquake
- Fire Punch
- ThunderPunch
I had Armaldo here. He worked really well but he had way too many weaknesses. I then tried Gigalith and then i realized that my team is very weak to Fighting types. I happily kicked Gigalith out and put in Golurk, a newcomer in the NU tier. He has 3 types that do nothing on him and that is very good. This set takes advantage of his ability, Iron Fist. Shadow Punch is STAB and coverage against Ghost types. Earthquake is also STAB and hits very hard with Choice Band and all the other stuff. Fire Punch and ThunderPunch are there because they take advantage of Iron Fist. I had Stone Edge here before but the two Elemental punches cover everything that Stone Edge covered but in better. I am thinking of incorporating Zen Headbutt somewhere in there so i can switch in on a Fighting type and use Zen Headbutt after.

Machoke @ Eviolite
Trait: No Guard
EVs: 252 Atk/ 252 HP/ 4 Def
Adamant Nature (+Atk,-SAtk)
- DynamicPunch
- Bulk Up
- Bullet Punch
- Payback
The only survivor of my original team. He really saw everybody coming and going away from my team. DynamicPunch paired up with his ability No Guard hits very hard because it is STAB and it automatically confuses the opponent. Bulk Up powers up every single move here. Bullet Punch is for finishing off opponents that are left with low HP and the priority thing helped me a lot. Payback is for coverage against Psychic types.
That is the end of my NU team! All kinds of advice is accepted!
