Ninetails's role is to be a sun setter as also to healing wish when it is needed and can also dish out a lot of damage when using overheat. I have chose Torkoal over Ninetails because Ninetails can use relatively fast Wisps. And hit things like Great Tusk, Kingambit, Landorus, and many other slow physical attackers.
Walking Wake is a special sweeper when you get a clean switch in with walking wake you can proceed to sweep most teams. Walking Wake can 2HKO Zamazenta and tank a +1 Body Press in the process. Walking Wake hates seeing Ogerpon-Wellspring on the preview because of Water Absorb. Walking Wake can also OHKO many Pokemon with Draco Meteor. Tera water can be used to 1v1 opposing Walking Wake and do more damage with Hydro Steam.
Gouging Fire is used as a banded sweeper than get pretty much KO everything if you use raging fire against +1 Zamazenta it will be a 2HKO, also with enough speed to out speed Dragapult and Zamazenta when in the sun. Stone Edge can be used to OHKO Moltres. Raging Fury is a 3HKO against Alomomola and can get it in very low HP.
Venusaur is a sweeper also can be used to KO Enamrous which this team can struggle with, and also KO a major threat Iron Valiant with one weather ball no boosts needed. Venusaur's weather ball is a really good coverage move against Skarmory and Corvinight with Venusaur would struggle with. I also chose Sludge Bomb instead of Earth Power because of the teams weakness to Fairy types.
Great Tusk can be used as removal also as a sweeper, but do not rely on it because Hattrene can bounce hazards which this team doesn't have. Great Tusk can not usually beat Corvinight and Skarmory but with Temper Flare Great Tusk can one shot if you fail a Headlong Rush before the Temper Flare, Same can be used against Gholdengo and Gambit (if needed.)
Lastly Hatterene can be used as a hazard bouncer, para bouncer, and a pivot with the Eject Button item and can 1v1 Zamazenta. Hattrene is very important to be a pivot into Walking Wake or Gouging Fire. Also can bounce back Sticky Webs from Ribombee which Great Tusk might not be always able to Rapid Spin away due to Gholdengo.

I added choice band speed boosting Roaring Moon with tera ground, this is a fun choice as it basically punches huge holes when your opponents are expecting you to set up. This also gives a little bit of pivot pressure with U-turn. Finally tera ground lets you dodge potential revenge kills from Raging Bolt as well as thunder waves from Dragapult or others.
