Hi! Your team looks pretty solid, I just have a couple of suggestions.
I like your Durant set, Thunder Fang should be amazing because or how strong Lapras seemingly will be, plus it blocks spore from Amoonguss. You can consider running Rock Slide over Stomping Tantrum for Charizard, although Helping Hand + Max Lightning might KO as well. It’s up to you.
I personally like using a Bulky Talonflame with Taunt, especially on this team since it seems to struggle against trick room. You can probably drop Flare Blitz and the attack investment, although if your worried about Durant Mirrors, Flare Blitz is better.
Dracovish looks good, but do you really need Dragon rush? It’s a very risky move to be locked into, and it doesn’t even get the strong jaw boost (I think). Ice Fang or Leech Life are probably good. Rock Slide is also changeable.
On to Comfey.
EDIT: I am changing my suggestion to use Clefairy due to already having Amoonguss for redirection.
Since Comfey is mostly used for support, you don’t need draining kiss. You can choose between trick room, taunt, ally switch, or protect. Otherwise, it looks good.
Amoonguss looks good, just make it min speed for added trick room threats.
If you’re not using Grimmsnarl that often, you can consider Gmax Lapras. It has the screens effect and pairs well with tailwind or Comfey. This doesn’t really improve your Urshifu matchup, though, so I’d recommend keeping Grimmsnarl, or Sableye. Against Talonflame/Urshifu Teams I’d lead Prankster + Dracovish. You can fake out and Fishious Rend Talonflame turn one for the KO. I personally might use Scary face (and maybe Taunt or Protect) over screens to further assist Dracovish’s Fishious Rend. You can then consider Band over scarf, but scarf is probably better.

Gameplan
You will almost always Dynamax Durant on this team. Usually Comfey plus Durant is a good lead, but if you need speed control, You can use Prankster or Talonflame instead. Dracovish is a strong Pokémon to have in the back, as is Amoonguss. Grimmsnarl is also good support to Dracovish.
This team looks very strong and adaptable, very impressive for a new player!
Hope this helps!
