If you would give me some advice of how I could improve my team, it would be greatly appreciated.

Your team is really good when it comes to typing. There's a really good balance.
But the first thing I notice is that you have one special attacker. Although it is a special sweeper if Hydreigon is defeated you get completely walled by physical walls. The biggest problem is that all the other pokémon in your team are physical attackers, so maybe you need to change up a few things to see if you can get atleast 2 special attackers.
Other than that it looks really good. I don't see any more problems with it, but you always need to battle with it. By battling with a team you can see what your team is weak against and what you maybe need to change.
So good luck with your team and maybe we can battle sometime.
