Weezing-Galar @ Wide Lens / Sitrus Berry
Ability: Levitate
EVs: 252 HP / 252 Def
Bold Nature
Tera Type: Fairy
IVs: 0 Atk
- Acid Spray
- Strange Steam
- Protect (if it has Earthquake)
- Will-o-Wisp / Taunt / Clear Smog
Levitate Galarian Weezing hard walls Dragon Sceptile. Resists Grass, immune to both Dragon and Ground, and Sceptile's other coverage moves hardly do anything to it, even after Dragon Dance.

Ability: Sap Sipper

Azumarill @ Sitrus Berry
Ability: Sap Sipper
Tera Type: Fairy
EVs: 252 HP / 252 Def
Bold Nature
IVs: 0 Atk
- Charm
- Chilling Water
- Helping Hand / Misty Terrain / Protect
- Fake Tears / Protect
Offensive and supportive Sap Sipper Azumarill will do well here, although boosted Thunder Punch is something to worry about. No Huge Power means it'll be a bit weak even at +6, though, so keep that in mind.
Ribombee @ Light Clay

I'm deadass, yo. The only thing you'll need to worry about is Acrobatics, but if Sceptile isn't running it, Ribombee hard walls it, too. Shield Dust even prevents Thunder Punch para.
I do not believe that Protect will be necessary for Sap Sipper Azumarill's success under most circumstances. Based on past Grass raids, when the reset happens on a time gate or by another player, the boss's move is already decided for the turn, so it won't be able to pick a new move based on the removed ability until the next turn where the ability is back and just hits into Sap Sipper. If it happens on a damage threshold by attacking the boss, then the ability reset will be removed at the end of the same turn, and the boss will just use the move that it already selected at the start of the turn. So Azumarill should not be taking a Grass move on a turn without Sap Sipper, unless it's so early that the boss hasn't visibly revealed Sap Sipper yet to know not to pick a Grass move (like Hisuian Decidueye), or it comes late enough for a random second attack to trigger, which at that point Azumarill should be tera Fairy, or the slim chance that Sceptile has no moves that can damage Azumarill normally (maybe if it has Earthquake and a buff) and just picks something random anyway. Though there's not much in competition for the 4th moveslot, I would probably consider run Tail Whip/Tickle or even Liquidation with damage and time being a potential bottleneck.

Glad to see a good Turtle set :)I see your Butterfly and reply with Turtle
Enamorus-Therian (F) @ Shell Bell / Fairy Plate / Metronome / Covert Cloak (if Rock Slide and want to not risk flinches)
Ability: Overcoat
Tera Type: Fairy
EVs: 252 HP / 252 Def / 4 something
Bold Nature
- Draining Kiss
- Iron Defense
- Calm Mind
- Moonblast
No support here, just damage (probably better for solo)
0 Atk Tera Dragon Sceptile Leaf Blade vs. 252 HP / 252+ Def Enamorus-Therian on a critical hit: 43-51 (12.2 - 14.4%) -- possible 7HKO
0 SpA Tera Dragon Sceptile Leaf Storm vs. 252 HP / 0 SpD Enamorus-Therian: 72-86 (20.4 - 24.4%) -- guaranteed 5HKO
0 Atk Tera Dragon Sceptile Rock Slide vs. 252 HP / 252+ Def Enamorus-Therian: 66-78 (18.7 - 22.1%) -- possible 5HKO
Rock slide is probably the scariest attack to deal with, and honestly still gets neutered by the Iron defense boosts anyway. Toss in intimidate support and you should be fine.
Could tecnically run Agility over Moonblast to outspeed but I hardly doubt Draining Kiss would have enough PPs.
If it doesn't have rock slide I don't think it gets free-er than this honestly.
I think Emboar's HP was inflated more than other 7-star raids only because most of its base moveset used Reckless-boosted recoil moves.I'm not too worried about Azumarill's damage output after actually looking at Sceptile's bulk unless they crank up the HP to compensate following Emboar's 40x…
You're right that Sceptile's special movepool is limited, but its physical movepool is more diverse and has some great options. The lack of Steel-type moves is a big drawback, though.I can see this going Mixed or Physical. Despite having a higher Special Attack, Sceptile's Special movepool is abysmal on the coverage side, with Focus Blast being the only worthwhile coverage move it has beyond its STABs. Meanwhile, its physical movepool is colorful (Earthquake, Thunder Punch, Rock Slide, Throat Chop just to name a few) and it has Swords Dance. Notably, Sceptile doesn't get any Steel-type moves, and therefore can't hit Fairy-types super effectively.
Realistically speaking, if the boss isn't mixed, I don't think you actually care of Snow after the start. Reflect and Aurora Veil are basically same if the boss is phisical only, sure you miss out on the snow boost, but you probably can EV yourself to live long enough to set up the chilling waters.The main thing holding Ninetales-A back is that you can't fit all these moves in one set, especially if you want to renew Snow with manual Snowscape. The other thing is that Ninetales benefits most from Ice type teammates that can also utilize the defensive boost from Snow but most of the good options seem to be Fairy types.
