All right, this already has two answers, but I would say Yes. Why? Because he will plow through the first two Elite Four, and it can hold its own against Flint's Drifblim. The fourth won't give Abomasnow too much trouble, and Champion Cynthia's Garchomp and Roserade don't appreciate Ice moves. Not to mention her Grass hating Milotic. So yes. I would use it.
