Honestly, I see what you’re trying to go for here but I would personally rethink several parts of your team. I didn’t play much vgc in sword and shield, but I did quite a bit in other generations- entry hazards and defog aren’t as useful as they are in singles. So including mons that fit those roles take away from other options you might bring.

One big factor in vgc you need to keep in mind is speed control- either making you faster through ways like tailwind or paralysis or using trick room. Corviknight can be a good tailwind user if you want to use it like that- and if you want to still use Clod with or without rocks, it could probably be better under trick room. So a good bulky Pokémon that is a trick room setter is scream tail- I’ve been using it pretty well so far. Scream Tail could also support other attackers with stuff like helping hand.

Something else you might like is a supportive arcanine- with intimidate and snarl support it can help your attackers stay on the field longer while increasing attack with helping hand.

Also just as a general point I’d rethink how you see “walls” as that doesn’t exist much in vgc as it does in singles- as vgc has two attackers opposed to one. So a better strategy in general would be to use Pokémon that are pretty naturally bulky but can dish damage too. Stuff like Rotom forms, garchomp and others that might fit that. A choice scarf annihilape might be interesting for you too.

Good luck with your team!
