Is this a good team comp for pokemon black/white?

call me the master ive beat every game and here i see a few weak spots in your defense i see 2 water types and you onley need one or a double grass or electric team will bust through forretress needs to forget payback and learn explosin becuase of its high defence and becuse it has sturdy and also give it the left over ditch the milotic and get a tortera so you have a defensive attacker who can take water types better
