>>32900826i was skeaping on air. i marely gave a few reasons for its usefullness. as for rain-
1. predicting enemy drizzle on your sun
2. running a rain team, keeping shiftry for variaty
3. keeping rain in your team simply because too many of your mons hate fire
at any rate, bug moves aside, since shiftry got moves for heal you can go quite bulky with it. and because it has access to moves like nasty plot, it can still set up and sweep, no evs needed in offense.
tough generally, use it in sun.
