Im new to making a Pokémon deck, could somone help me make this deck better?

So I've been playing the Pokémon TCG on vrchat (Link to the world – https://vrchat.com/home/launch?worldId=wrld_5f51d429-bfed-4e91-8a25-40c8cdcdbd2e&instanceId=37998~region(use)) ), and i want to make the deck better, but i have zero idea how to do that. Could somone help me or give me some tips, please? i don't want it to be meta, I want to play with my friends.
