Azumarill: I'd expect to see a bunch of people pull out their old lizard-slaying bunnies to fight the newcomer veteran bunny with the same strategy as before. Gunk Shot could be scary if it comes up, but since Cinderace is physical, Azumarill's access to Charm and Tickle give it some extra support utility this time.
Skeledirge: Bulky and resists Pyro Ball, though Sucker Punch might hurt. The strategy with this thing is to click Torch Song repeatedly. Slack Off, Will-O-Wisp, Mud-Slap, and Helping Hand can round out the set, but you can also just slap on a Metronome or a Choice Specs and go to town.
Slowtwins: Can Belly Drum themselves, but it's way funnier if you use Psych Up on an ally that already used it. Atk isn't great but makes up for it with bulk and support options. For those lacking internal dawgs, special attacking sets can boost up with Nasty Plot. Slowking's Def is a little worse but it's the best Reflect user because Slowbro can't learn it in SV.
Annihilape: The play here is to spam Screech for the benefit of physical attacking allies, then start throwing out Rage Fists. Needs physical bulk investment to take the edge off Pyro Balls, but at least this time it's not weak to one of the STAB moves. There aren't many bulky Screechers that aren't weak to Fighting, so this is as good as it gets unless you want Koraidon to give Cinderace free sunlight.
Charcadet evolutions: Armarouge can throw up Psychic Terrain and gamer combo into Expanding Force. Ceruledge has Swords Dance to set up and throws out Bitter Blades. Both get Reflect, which is definitely an important support move, and Clear Smog, which could be used to counter Swords Dance or Bulk Up but might interfere with other strategies.
Dondozo: Doesn't resist Fighting but is too fat to care. Spam Tickle to assist other physical attackers and blunt the damage output, and eventually you can start hitting it with Zen Headbutt. Note that Unaware is bad in conjunction with Tickle and you want Oblivious or Water Veil. If Cinderace goes for Sunny Day, you can counter with Rain Dance and switch to a Water STAB.
Dachsbun: Yeah I know but it's actually better than last time, its physical Def is better than its SpD. Won't do much damage but can run a decent support set with its pick of Charm, Mud-Slap, Helping Hand, Howl, and Play Rough.
Goodra: Unless you want to run Eviolite Shellder this is the best Life Dew user. Has Charm as well Acid Spray, the latter of which can be helpful if allies bring special attackers. Won't do a ton of damage but should be a decent supporter. Acid Armor+Body Press is also an option, though it may be undone fairly quickly.
Charizard: Resists both Fire and Flying and can't be burned, but the lack of bulk means even neutral coverage moves will do a chunk. I'm thinking Sitrus Berry/Belly Drum into Acrobatics spam is the play here, since Zard can't boost its SpA outside of Solar Power. Swords Dance is also an option if you need juice but don't want to risk Belly Drum, and Smokescreen can sometimes cheese if it needs to.
Iron Hands: The classic raid drummer, should be able to eat a hit and get off a Belly Drum. Doesn't have resistances to Fire or Fighting so it's gonna have to lean on its physical bulk to pull through.
Grumpig: Has Thick Fat to resist Pyro Ball, though it might still get rolled by coverage moves. Gets Reflect, Mud-Slap, and Psychic Terrain for support, Nasty Plot to boost itself up. Kinda bad but maybe it works?
