TORUNEROSU (641)
Flying
Mischievous Heart (Non attack moves have boosted priority-serebii)
79 / 115 / 70 / 125 / 80 / 111
Possible set: Jolly, 31/x/31/31/31/31/31, 4HP/252SAtk/252Spd, LifeOrb/FocusSash, Tailwind, Swagger, Air Slash, Protect
Timid 252 SAtk / 252 Spd gets you 177 / 179 @L50 with bulk alot like Porygon-Z.
This mon has real potential to be a surprisingly good set-up and status mon with it's ability (allegedly) adding priority to non-attacking moves. If I understand correctly this could mean that (avoiding Fake-Out) you could slap a quick Swagger on their scarfer, set up Tailwind and let your partner immediately use it, throw up a superfast Sub, or even possibly shut your opponents choiced-speed-mon down with a priority torment. There are just so many possibilities here (priorityswagger being an interesting one to abuse :3)
