Pokemon Black and White Random Wifi. Starmie The Hero

Well I think that my opponent didnt choice the pokemons very well, my starmie was effective against all his pokemon and for this reason, Starmie could beat all. But i think that Starmie is a good pokemon, his speed and special attack are very high but for other hand, Starmie has a defense and hp very weak. I used Starmie, Metagross and Electivire My opponent used Heatran, empoleon and weezing
