Is this a good team for Pokemon Platnum?

well first rotom is a terrible pokemon if you want an electric type i would get a luxray or electrivire because they have great attack.also as your sixth pokemon i would get a flying type because trust me your going to need somebody to know fly so i would try to get a staraptor,noctowl,honchkrow,or a gliscor (i have all of those and there really tough).
