Might as well take a shot at this.
Urshifu: Get rid of Aerial Ace. It's not going to do anything significant for you. Replace it with Sucker Punch, Close Combat, or even U-turn.
Ferrothorn: Looks good to me.
Slowbro-Galar: Quick Claw + Quick Draw is really gimmicky, and not the greatest idea most of the time. Use Regenerator and Black Sludge instead to heal up. If you want to help out Ferrothorn a bit more, consider replacing Yawn with Trick Room. This doesn't go too well with the rest of your team, however.
Dracozolt: Looks good to me.
Rotom-Heat: I think Rotom-Heat is better as a standard Nasty Plot or Pain Split set user. If you want to keep the basis of this set, consider Shadow Ball over Dark Pulse for the chance to lower Special Defense. Dark Pulse is quite good, though.
Tyranitar: Consider Heavy Slam over Iron Head. Either works, however. I assume Rock Blast is to get rid of Substitutes and Sashes? With the offensive set you're going for, this could work, but I think something like Fire Punch would be better, in order to cover its Bug and Grass weaknesses.
That was my first team rate, so feedback is greatly appreciated. Hope I helped!
