If it gets a Mega, I REALLY hope it doesn't get No Guard. If it does, I'm packin' a Scarf'd Articuno with Sheer Cold. --- I was once modded for illegal activity because I made a topic asking for advice on nicknaming my Pokemon. 3DS FC: 5043-2277-6391 - THIEF
Generally, Starmie is either used as a fast sweeper, or fast rapid-spinner.
In either case, you'd have to max out the speed stat on him, which puts him ahead of a vast majority of pokemon. Analytic would be almost useless.
