How does Ice Beam work well with Hail? Hail is not like Sunny Day and Rain Dance, it doesn't increase the power of Ice attacks. Also, there is really no point to having Vaporeon know both Rain Dance and Hydro Pump, Hydro Pump would be used instead of Surf because of the already high power which doesn't need to be any higher if it means wasting a turn. Also, Vaporeon is getting damaged by Hail, Hail is only good with Pokemon who won't be affecteed by it, either through typing or moves. Both Shadow Ball and Shadow Claw are not needed on Froslass. Nor is both Ice Beam and Blizzard. You only have two move types on Froslass. A good option would be to add in a Pokemon that knows Surf but is not a Water type, to heal Vaporeon with Surf while attacking the foe.
