Cloyster don't need 6 statistics at 31. It only use effectively his Sp.Atk so you can forget about physical atk. I will let others help you with the movesets.
Hello! I'm Irda nice to meet you. I have just begun the game and I thought it could be a great idea to create a forum account too. I'm quite shy so I don't speak much ^^
My favourite starter is Squirtle and my favourite region is Kanto. I hope to see you all in game or here!
