This is my team for regulation h.

the team does seem okay for someone just climbing from PokeBall tier up

You should probably replace Rillaboom and Palafin with Tatsugiri and a tailwind setter.

If you want to keep Palafin, I recommend pairing it with Incineroar, or Hisuian Arcanine, and Amoonguss or Rillaboom for a powerful Grass/Fire/Water core that rely on switching to improve their defensive and offensive power.
