Volcanion still does have a respectable Attack base stat of 110, and a moderate Speed of 70, so you could probably make it work. It also has a decent physical movepool, consisting of moves such as Flare Blitz, Earthquake, Stone Edge, Flame Charge, Brick Break, or even Superpower. You could probably still run Steam Eruption with the high base power as a mixed sweeper. Scarf could be a good item to boost its mediocre speed, and a full attack set as well.
