When you start the best place to go to 1 of the caves because there are many types of
pokemon including unknowns. You can catch Shiny,Dark,Metallic and Ghostly pokemon randomly
throughout the game. Try t kepp your pokemons levels around the same and try to hav at
least 1 of fire,ice,phsic,ground,bug and 1 of your choise in your party.

Hoping it helps, if you hav a question message me on pokemon crater my account name is
