I am trying to get battlepoints from the PWT. Most of the time my skarmory beats the entire other team, but occasionally he is taken out by an electric, fire or water special attack. I need reccomendations for my two last members, hopefully stuff I can switch into attacks that would have killed skarmory. I am thinking swampert could somebody suggest a build for him. Please don't suggest changes for the skarmory or suggest I put in legendaries.

Skarmory
- Roost
- Bravebird
- Spikes
- Whirlwind
Item Attached: Rocky Helmet
Trait: Sturdy
EVs: 252 HP / 252 Def / 6 Atk
Relaxed Nature (+Defence, -Speed)
