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

i think its a good idea, i never played black and white so i have no idea the pokemon you mention but the moves sound pretty sick. On forretress, i would do earthquake its a 100 percent landing on an opponent, except for Flying monsters. and on starmie maybe instead of thunderbolt do thunder cuz its more powerful but even if you don't change it its a pretty good combination you have. :)
