I´m not gonna sugarcoat iit.
- Diancie is a solid physically defensive mon whose secondary typing is very useful in the Dark matchup and gives you a small glimmer of hope in the Fighting matchup, one of the Four Impossible Matchups for this type (Fighting, Steel, Water, Ground).
- S tier mon on this type. You need this for sand and every serious rock team should have a tyranitar. I've chosen Assault Vest for this team and pretty much walls every special attacker that doesn't have a STAB super effective attack (which you're probably thinking ?? since it has 7 weaknesses but it takes hits very well and hits back decently hard in return)
- Always been the better form in this meta sorry not sorry. For a type that has fundamental issues, you need as many wincons as possible and Dusk does not have Sand Rush. This lycanroc can go Adamant and outspeed the entire tier under sand while having a great damage output with good coverage in Close Combat and Play Rough and priority in Accelerock to revenge kill weakened threats. Its also your other shot at beating Fighting as Play Rough spam will ohko the frailer mons on the type like Valiant.
- Rock's special wallbreaker and Spikes setter. Mainly used as a suicide lead in most circumstances so you can possibly force tspikes up with its ability.
- God-send mon for the type. Fire is generally useful for rock to have access to threaten Grass and Steel teams and the other Fire type on this type was
.. Enough said tbh. The Fire typing also offers a neutrality to the aforementioned types and prevents Scizor Bug from getting the win instantly. Choice Scarf is very threatening, offsetting Arcanines average speed tier and basically making grass a free win (Not much of an achievement since grass is a bottom tier type but let rock get its wins.)
- I haven't been too impressed with Kleavor overall as a mon tbh but this type already struggles with varied options so here it is. It does hit hard and Stone Axe means I don't have to waste a slot on rocks on Diancie or Glimmora.

https://replay.pokemonshowdown.com/gen9monotype-1898342899-q1e31uqdap29unwrhicstygdym13s0jpw - Vs Ghost. Rock actually pairs well into Ghost despite the Gholdengo on most Ghost teams. Counterplay was dicey since they decided to crit my arcanine.
Definitely the best version of the team so far. The 1000-1300 range is a mixed bag to solo rock with but there's so many bug teams low ladder.
Urshifu water
(still great team tho!)
This thing is an insane wallbreaker. It decimates fatter team archetypes like Poison or variants of Water, which is a godsend for Flying teams. The amount of switches it forces allows Nasty Plot, its new pickup this gen, to shine. It has just enough coverage to smack anything trying to switch in, and even unboosted, it packs a serious punch with Nasty Plot + Life Orb. 
This is a set I frequently used throughout SS, and it has served me well. It provides speed control, and Galarian Zapdos is no slouch of an attacker in its own right with its 120 BP STABs, U-turn, and Thunderous Kick to force progress. I don't have much more to say about this - it's just a good pick overall. 
HO Flying teams do want Enamorus for Healing Wish, but I chose HDB over the more common Choice Scarf since I already had Galarian Zapdos filling the role of speed control. Healing Wish is a godsend, as you can get your wallbreakers another chance to decimate teams. Meanwhile, Enamorus appreciates this team's ability to break Steel-types down, letting it potentially sweep late-game.
While Corviknight may seem out of place on a HO team, it's absolutely necessary for any archetype. It provides a bastion of defense against threats like non-Thunderbolt Flutter Mane, Dragonite, and more. It also functions as a great lure for things like Gholdengo and Toxapex, which this team handily takes advantage of. Finally, being able to get rid of Stealth Rock is what holds this team together in longer games. It's the perfect glue for any Flying archetype. Being a Ice neutrality really helps as well.
Tornadus-Therian provides multiple things to this team. Firstly, Regenerator is an insane ability, letting Torn-T outlast bulkier teams that aren't threatened by Landorus as much. Secondly, it is a fast pivot with U-turn, meaning that not only will it heal itself, it will bring in threats. Finally, it's not a bad attacker at all with Bleakwind Storm's Speed drop chance causing 50-50s of "Do I bring my wallbreaker in and risk a Speed drop?" It's also yet another incredible glue for Flying teams.
Dragonite is the final piece of this team. Its sweeping capabilities with Dragon Dance and its myriad of coverage is unmatched, and it synergizes well with the rest of the team since it appreciates bulkier cores being broken down before it sweeps. It also functions as a good defensive option with Multiscale. You can run Roost over Earthquake since this team beats Steel quite easily.
I'm not going to insult your intelligence by spelling out everything Torkoal does for Fire, but I will point out what it's not doing on this team: no status moves. Stealth Rock is a no-go since I'm relying primarily on Court Change for hazard removal (and I personally find it more philosophically poignant to only make my opponents suffer the hazards they use, anyway), Yawn is sketchy when 2/3 of my team, Torkoal itself included, can randomly inflict Burns, and Will-O-Wisp becomes a dead slot once the Burn is already set (or against other Fire-types). Instead, Rapid Spin and Clear Smog are used to heckle opponents who would disrespect it by setting up on it. Flare Blitz is Torkoal's hardest hitting move barring only Overheat, and Earthquake threatens most things Flare Blitz can't. This is of course far from the only way to build Torkoal, but I think it works nicely for this particular layout.
This is how you don't die to Walking Wake. While Volcanion always has had good qualities for Fire, including its typing, ability, and movepool, Water Absorb is frankly a must-have to deal with Hydro Steam, in or out of Sun. Assault Vest with heavy SpD investment lets it live and outrace Draco Meteor or Dragon Pulse, on the switch if its Spe is higher than its SpA. Solar Beam is your best option when the Sun is up, and Sludge Bomb and Earth Power are your best options without it. Steam Eruption is unfortunately not cheap in the same way Hydro Steam is, but it does help make Volcanion a bit less weather-reliant. Alternatively, Weather Ball is your best Fire move in Sun, but you do basically go all-in on Volcanion needing weather to function.
Mostly opting out of Libero because Normal-typing from Court Change is awkward. Pyro Ball, U-turn, and Sucker Punch are all must-haves in any Cinderace kit.
I searched for the fastest Fire-type with a move super effective against Dragon and gave it a Scarf. The rest of the movepool writes itself: Trick ruins the day of any defensive or set-up mon (and that fills me personally with glee), Psyshock is a non-Fire STAB which incidentally lets you hit special walls (which you may or may not have tricked your Scarf onto), and Fire Blast is just plain your strongest spammable move in Sun. Oh, and, Max Spe EVs while Timid gave it an odd-numbered Speed value, and given its relatively unique Speed tier, I figured it'd be worth taking a single point just to ensure having 4x+1 HP. Old 
I'm gonna be honest: Magma Storm is purely me being extremely petty against stall. It does have a nice quirk against Water, however: you guarantee the safety of clicking Solar Beam, by disabling the option to switch into Pelipper. Plus, breaking Forretress and obvious Sash users in a single turn 75% of the time instead of, like, 30% is always nice. 75% Accuracy is extremely painful, however, especially when it's your only option to hit something like a Corviknight. Physical bulk investment does make those Body Presses slightly less painful to deal with, but, the reason you're using Heatran in the first place is as an answer to opposing Rock-types, which are mostly physical in nature, and possibly even a Ground-type or two while the Sun is up and you still have Air Balloon. Basically you lead Heatran whenever you see something like an opposing 
Banded Extreme Speed. That's basically the entire reason this is here. Of course, mono-Ghost is a thing, so we're going to need more moves. Raging Fury is your hardest-hitting move against most things, most Ghosts included, especially in Sun, and Outrage hits basically everything else. Close Combat is coverage against Rock-types specifically, but it's nice to have against Dark, too. This thing is the very definition of a lategame cleaner. While Hisuian Arcanine is slightly stronger, it is also slightly slower, and possesses double weaknesses to both Water and Ground, and I'm not about to have two double-Ground weak Pokémon run on the same team.
