This is just a normal play through of Pokémon Moon. Except you help decide my team except for my starter which is Popplio. Each person may choose one Pokémon and choose it's nickname
If your using Popplio, then catch a alolan diglett, the steel type helps deal with poison, and the ground type helps deal with steel types, a great Pokémon to have to counter Primarina's weaknesses later down the line.
