S

- I'm not 100% on volc being S, Fire doesn't feel like it has many required mons at all but it's defensive utility and Water stab is always great

- I really don't see a good reason to ever not use Tork here, the sun setting and utility role compression can't be replicated by anything else
A

- Pretty consistent hazard removal and Ground counter with it's speed and (inconsistent) priority

- Valuable breaker with good bulk, a great typing and set variety (choiced, bulk up and z moves all function in my experience)

- Loves not having to deal with Heatran, Scovillain is much more consistent as a sun sweeper with specs or growth

- Best mega evolution by far, strong special breaker that becomes ridiculous in the sun
B

- Speed can let it down but this thing hits like a truck and the Electric immunity is great (needs removal support tho)

- On teams that want as much sun as possible Ninetales is a legit option, it can hold heat rock while Tork has boots for more consistent removal and healing wish is excellent utility

- Niche but I can see the potential as a scarfer or banded breaker (strong priority too)

- Screens, Ground immunity, removal, not bad
C

- Better on Poison but the sub toxic set can just 6-0 ppl sometimes so it has use

- Chandy can probably cook here, it's the best tr setter and has good set variety

- I can see the potential of a Trick room team with this and Marowak + it has decent defensive utility

- Eruption go brrr

- Eruption go brrr (but ghost so it might be decent actually)

- Rocks, Fighting type, good mixed coverage, fast, idk it has traits
