This is such an awful justification. Ferrothorn is OU, and so is Forretress, and both are SUPER common in Ubers. Not to mention that Scizor and Tyranitar just got a ton more useful with Soul Dew out. Like Scarfty's damage is even going to give you any HP back in Ubers, unless using like Heatran or something. And you said it yourself, Shed Skin cures status, so why not use Rest to get FULL HP back? Then you have 1- or 2-thirds chance to cure yourself.
