meh idk, I think its just one of those hi-risk strats, such as my endure-reversal-salac-blaziken. Yeah they pack a hell of a freaking punch, but if they're countered they just do horrible
So even if they can be good they can suck pretty much too, and considering how easy that would be to counter this using the right moves and pokes I kinda doubt it should be uber. Just use gradual damage moves (burn or curse) and its out
