Physical Toxicroak is honestly a "meh" rain check.
The special sets (i like specs, but the NPer works well) with Vacuum Wave are much better at that since it prays on the lower special defense of most rain dance sweepers and can actually bypass getting OHKO'd by Kabutops due to being able to snag it with V-Wave before it gets a chance to stone edge. V-Wave also stops Omastar well and Sludge Bomb hits the rest such as Ludicolo, Gorebyss etc hard and the only thing on Rain Dance teams that resists Poison/Fighting swift swimmer wise is pretty much Qwilfish who doesnt like Shadow Balls/Dark Pulses.
I've always liked the special set more then the physical and it is probably the best counter for RD there is possible. It can come in on the RDer (providing it's not Uxie) set up and have fun.
Vacuum wave gets an easy K.O on Kabutops and Omistar at +2. It can K.O qwilfish who can't do anything back other then explode. And ludicolo can't K.O whilst your at full H.P as you K.O back with sludge bomb. The only sweeper it has problem's with is Gorebyss.
