Here is my suggested set:
Wild Bolt-A sweeper won't last long anyway, might as well do a lot of damage.
Swagger-Boosted attack won't really make much of a difference, seeing as this guy has pitiful defenses.
Overheat-A good, unexpected move. Since you won't use it often, the stat drop won't bother you much, (all the other moves are physical)
thunder wave/Pursuit-Thunder wave can cripple foes for your teammates, or you can use pursuit since the foe will likely switch to a ground type for coverage, so you can easily predict when to use it.
I actually like this set as well, so I'll have it as a gimmidk
- Rain dance
- Hidden power [water]
- swagger/thunder wave
This guy has too many speed boosting moves IMO. A trick room would kill him, he's already got high enough speed.
