I am thinking of using Scald over Surf for Starmie
Some reason i like to play safe and with Starmie's average defence it can work, but as you say surf is still powerful with Stab and its better to faint there pokemon then burn them.
I really dont know what to pick, the fact i will be double battling is spurring me to Scald as the other partners wont be too good against water, but then gain can work with special wall.
I dont know, hmm
