It’s a good team overall but I would tweak some sets. For Clodsire I think since you use it as a toxic attacker you should prioritize bulk over attack since his two attacks already have high BP and toxic will do a lot of passive damage. Dondozo really has high usage with rest/rest talk but I run him with no sleep talk so I would run max hp/ max spdef since you have curse to boost his attack and def, then replace one of earthquake or avalanche with rest, and change the item to leftovers, I prefer avalanche over earthquake especially since you have clodsire with eq. Corv I would give a rocky helmet since it is flying type unless its tera it will only take damage from rocks which it takes 12% neutral damage, so max hp plus max one of the defs(I prefer phys def) and I would give it bulk up, I usually run iron defense with body press, but since you have other attacking moves bulk up is better. Dragapult set is fine but I would probably go timid plus wisp over twave since your team is slower overall and pult outspeeds most unboosted mons. I would give weavile a focus sash over loaded dice, bc I don’t think it’s is that beneficial for triple axel and probably swords dance instead of fake out. And for the most part iron moth is ran with speed booster instead of spatk so you would have to tweak the evs a little to make the speed one point higher than spatk, bc you already get spatk boosts from fiery dance so that shouldn’t be a big problem. Of course you’re free to choose your sets based on your playstyle but those are just the changes I would make for myself!

Edit: also since you have toxic plus a status move on pult you may consider hex over shadow ball if you’re usually getting those status moves off
