It's not in OU, for sure.
It's not even viable in OU since a bunch of the pokes are not grounded, another bunch is slow but bulky as fuck, there's defog and rapid spin on every team, everything has priority, the only two would be viable setters are awful and there's Bisharp who's too big of a threat to just go and boost it's attack for free every time it switches in.
Maybe it'll be viable in lower tiers. Broken I doubt.
And don't even think of calling me smogonfag and similar names, it's even less useful in VGC and Battle Spot.
