The Steamer denies water moves and takes virtually no damage on Ice fang (and dodges 2hko on psy), only fearing Close Combat from Barraskewda. Skewda can only 2hko though, and Volcanion can just KO back after stomaching one. Volc's also a perfect fit for hail (still viable), a playstyle that matches up naturally well against rain.
