Rhyperior OHKO's or 2HKO's all of them, and the worst they can do back is an UNSTABed Surf from Dragonair.
That's off the top of my head.
I seriously hope that post was sarcasm. Shed Skin is in no way broken. Although ShedRest Scrafty, if it ever fell into UU, might be another question.
On the topic of Blizzspam, it itself is good, but not broken. It may seem broken right now, but that, in my opinion, is only because of Froslass, who has several suspect sets, and isn't helped by Snow Cloak, or removing the Fighting weakness Blizzspam suffers.
Thunder Wave and Sub sets are a pain, and so is Spikes, and D-Bond... hell, Froslass could even be a complete troll with it's speed, Snow Cloak, and Confuse Ray, to net easy Spikes, and shuffle teams.
I can see it now:
Froslass @ Leftovers
Snow Cloak
Timid Nature
252 Sp.Atk/252 Speed/4 Filler
Confuse Ray
Substitute
Spikes
Blizzard
Ragequits everywhere. It's basically UU Jirachi. If not worse, due to the Sub.
