I edited your team a little bit, I didn't change anything but I made it easier to read and it looks pretty now :)
Scizor - Baton Pass Scizor isn't bad but it is outclassed by CB Scizor or a Swrods Dance set, the latter of which I am going to recommend.
Scizor @ Life Orb/Leftovers/Flying Gem
EVs: 252 HP / 252 Atk / 4 Spd
Adamant Nature (+Atk, -SAtk)
- Swords Dance
- Bullet Punch
- Bug Bite
This Scizor is rather striaght forward, set up Swords Dance and sweep. 252 HP EVs give great bulk, and the speed EVs are for outspeeding other Scizors running 252 HP and 4 EVs in a defensive stat. Bullet Punch and Bug Bite are STABs and both are boosted by Technician. If you run Superpower to hit other Steel types then it's your choice of leftovers for recovery or Life Orb for some extra firepower. If you run Acrobatics, go with the Flying Gem. One might question the use of Acrobatics as it allows Steel types to wall Scizor. The answer, it is extremely unpredictable, and it nails hits really hard after a Technician boost and a Flying Gem boost. Superpower is still probably the best option for coverage, but you already have a fighting type and a fire type for steels, so why not try Acrobatics?
Conkeldurr - As much as I like Conkeldurr I think Terrakion would benefit this team more, providing immediate crushing power with a Choice Band. CB Terrakion is perhaps one of OU's best wallbreakers and deals unfathomable damage with his STABs alone.
Terrakion @ Choice Band
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Close Combat
- Stone Edge
- Quick Attack
Basically how CB Terrkaion works, is you switch in on something that you either wall or threaten (And with a Band you threaten pretty much anything you outspeed) and select the STAB move that fits the situation best. At this point, nothing short of a physical wall will be taking your hits, and even they won't be doing so comfortably. While Terrakion is fast, make sure you don't keep him in too long, as he is a valuable asset for forcing switches and devastating the switch-ins. Just watch out for Ghost types. His STABs need no explanation, Quick Attack is for revenge killing, and actually works quite well, while X-scissor hits Psychic types.
Gengar - I love Gengar, but Hypnosis has low accuracy, and I am really surpised you didn't miss a whole bunch in the video. Replace Trick with Substitute, and replace Thunderbolt with Focus Blast. Last but not least, replace Hypnosis with Pain Split. You now have a fast sweeper with almost perfect coverage, you are hard to revenge, and you have recovery in the form of Pain Split. Another reason Hypnosis is unreliable is the sleep clause, and I am genuinely shocker your opponent didn't leave one of his pokemon asleep, as it would have rendered Hyponis utterly useless for the duration of the battle.
Dragonite - No Dragon Dance?! Wah? Dragonite almost needs Dragon Dance to sweep, and now that I took away the Baton Passing from Scizor, he needs to be able to boost his stats independently. Fear not, however, as with Mutiscale Dragonite can set-up 2 Dragon Dances with ease if played right.
*Dragonite @ Leftovers
EVs: 252 Atk / 76 SDef / 176 Spd
Careful Nature (+SDef, - SAtk)
- Dragon Dance
- Dragon Claw
- Fire Punch
Even though the Evs sacrifice some speed, the bulk is appreciated and aids Dragonite in Dancing ;). Dragon Claw is STAB and is more viable than Outrage in this instance because you are not the fastest thing out there even at +2 Speed so you want to keeo as much HP as possible. Fire Punch covers Steel types and Roost is for recovery, or you can opt for Extremespeed for revenge killing and priority what not.
Ninetales - I have never used CM Ninetales and TBH the team really isn't a sun team, so I am going to change him out if that's ok.
Rotom-H @ Choice Scarf
EVs:4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -SAtk)
- Volt Switch
Thunderbolt is main STAB and Overheat is secondary STAB that hits very hard. Trick is for crippling walls and locking enemies into support/boosting moves. Volt Switch is yet more STAB and revenge kills like a baws.
Metagross - I like Metagross but he shares weaknesses and no longer fits on the team. I notice you need something to take Water moves, and boy do I have the pokemon for you.
Gastrodon @ Leftovers
Trait: Storm Drain
EVs: 252 HP / 104 Def / 104 SAtk / 48 Spd
Modest Nature (+SAtk, -Atk)
- Ice Beam/Earth Power
Gastrodon can sweep teams with ease after just 2 Stockpiles, and with 3 the only thing he fears is extrmely high powered grass attacks, poisoning, and critical hits. Scald is STAB and has a nifty burn chance that is really helpful. Ice Beam hits Dragon type which wall you but Earth Power is STAB and stops you from being walled by things like Tentacruel and such. Stockpile is the crux of the set, boosting Gastrodon's defenses to untouchable levels, and Recover os for recovery, making Gastro incredibly hard to take down.
