Starmie @ Expert belt
EVs: 4 HP / 252 speed / 252 Sp.Atk
Timid Nature
- Surf
- Thunderbolt
- Ice beam
- rapid spin

This combination will turn starmie into a good anti-lead, the three attacks give an awesome coverage and rapid spin will get rid of stealth rock if something dares to set it up. I'd suggest expert belt over life orb since the lack of recover would only make last less on the battlefield.

changes in bold. the rest are all standard smogon teams so I don't know what to do about it since I don't really see a strategy there but the team does have a big fire/grass weakness (A choice scarf heatran would be able to rip through half of the team, not to mention it'll have problems with dragons such as kingdra, salamance and dragonite)

Thank you very much zero2exe!
my cousin wants to create a team for Starmie, so he suggested as teammates some Pkmn he has jet.... ready, he said.
But, however, if anyone can suggest some Pokémon changes to avoid this big fire/grass weakness this team has..... every help is much appreciated...... thank you so much! ;munchlax;

Not so much grass weak, just fire weak. Keep in mind on Porygon HP Water, Tri attack + HP water have complete neutral coverage. Just sayin'
