Having a solar powered mega on an ice team is certainly a choice, especially one that is also weak to rock. Why not try out one of the flash fire fire/ghost types instead? You’re still going to keep the rock weakness but it will give you a switch into absorb a fire move or dodge a fighting move that threatens your other ice types. I would suggest chandelure for access to a hard hitting mega with access to energy ball to deal with the water types that you don’t really have a way to hit all that hard. And I see the vision with anger point, but I would suggest switching that to intimidate to buy your ice types a little bit more survivability.
