Is he viable, I don't mean competitively I mean can you turn him into something nasty that could help me rip down battle tower. I want to have a more offensive mega beacuse my tank Mega Venoshocksaur just takes too long to kill people and is useless against steel

He can favor either attack or special But I'm not sure which way to go with him, also are there any non-ice pokemon who could possibly benifit from the hail effect?
