Rhyperior tried to sneak into Galar by disguising itself as a Coal Monster, huh? Jokes aside, this one has quite the movepool. Without Heatran, defensive Fire-types have more of a chance, and Coalossal could be a solid addition. While the typing does it absolutely no favors (4x Water weak, 4x Ground weak, Fighting weakness, Rock weakness all suck, though Ice, Bug, Fairy and Fire resistances are awesome), Coalossal tries to differentiate itself from Magcargo (who has the same typing and has forever been stuck in the bottom tiers) with some awesome support moves. Despite both being TRs in Galar, the combo of Stealth Rock + Spikes is rare, and Rapid Spin is also a rare move in Galar. Coalossal is the Pokemon that gets all three moves, giving it fantastic utility and role compression.
While a Spinner weak to Stealth Rock seems like a recipe for disaster, the new Heavy Duty Boots prevent Coalossal from taking hazard damage, giving it new opportunities to come in and spin, and maybe set up another hazard. Unfortunately, it is too slow to make use of the speed boost from Rapid Spin, as well as the max speed from Steam Engine (good luck finding a Water move you could get it from!). Suppose though that you've already got hazards on another Pokemon; afterall, they are TRs and have wider distribution than before! In that case, Coalossal still fits a support niche for your team. Spinning is still valuable given how common hazards are, and Coalossal can now spread burns through a variety of forms: Scald, Wisp and Flame Body. Scald is particularly useful as the burn punishes Water-types for switching in, as well as punishing Ground types not only with the burn, but also with super effective damage.
Offensively, it is held back by mediocre offenses (with no way to boost) and awful speed, so it won't be sweeping anytime soon. It does have enough options though to prevent it from being set up bait. Physically, it has options for both STABs, as well as Ground and Steel coverage, and Body Press (which works off of the 120 Def). On the special side, it doesn't have a Rock STAB, but does gain Scald. For a defensive Pokemon, it's sufficient.
--Pros--
Awesome support movepool consisting of multiple hazards, burns and spins
Typing has some options defensively, with key resists in Ice and Fairy
Spreads burns very reliably through Wisp, Scald and Flame Body
Unlike some spinners, Coalossal isn't passive
--Cons--
Slow as molasses
Many unfortunate weaknesses
Still slow even with Steam Engine boosts
No way to boost offenses
No recovery outside of Leftovers limits longevity, especially without Heavy Duty Boots to prevent hazard damage
*Dynamaxing potential*
Coalossal does have a Gigantimax form, which means it has an exclusive G-Max attack. G-Max Volcalith not only deals damage, but applies Fire Spin. Frankly, there are much better users of Dynamax than Coalossal, especially when using it in this way prevents it from utilizing its support tools.
Potential Movesets
* Basic Spinner *
Coalossal @ Heavy Duty Boots / Leftovers
Ability: Flame Body
EVs: 248 HP / 8 Def / 252 SpD
Calm / Careful Nature
* Rapid Spin
* Spikes / Stealth Rock
* Will-o-Wisp
* Stone Edge / Flamethrower / Scald
Pretty simple set: come in and spin, and set up a hazard while you're at it. Spread burns with Wisp, especially when you're set-up-bait for Pokemon like Gyarados or Barraskewda. Finish with a STAB of your choice (and change the nature accordingly!). Or go for Scald because
* Assault Vest *
Coalossal @ Assault Vest
Ability: Flame Body
EVs: 248 HP / 8 Def / 252 SpD
Sassy Nature
* Rapid Spin
* Stone Edge
* Flamethrower
* Scald
With burns from Scald supporting its physical bulk, an AV set can make some sense in becoming more of a tank. Spin is what gives this a niche, and you keep STAB for coverage too. Pretty basic AV set, with the Vest giving more options to come in and spin.
* Weakness Policy *
Coalossal @ Weakness Policy
Ability: Steam Engine
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
* Stone Edge
* Earthquake
* Fire Punch
* Iron Head
Putting this here because I know someone is going to try and bring it up. Not worth it imo but I guess I can't stop you. Basic premise is to try and take some weak Scald to trigger Steam Engine and Weakness Policy, giving you +2/+2/+6. With 636 speed, you can try and do a sweep. Not worth it for more than the memes for Youtube videos (because you know someone is going to try it)
