will always be great. But I can imagine Glaceon will be on almost every hail team spamming Choice specs Blizzards. I don't think Dewgong will be used, though, especially with Walrein being there. It is faster, but I don't like that merit as an excuse.
Why not add Kadabra to the non-Ice type Pokemon? He has Magic Guard, same as Duosion. And he is considerably fast compared to the rest of the nu pokemon, where he can either clean up after Blizzards were spammed, or take things out so Blizzard can be spammed.
That being said, Steel types would still be a problem (Mawil usage should go up. That would be fun), so Emboar or Sawk, as you've already put, should be on most teams. If not them, maybe
defensive Throh for the defensive hail teams.
@Nyara, I don't think offensive Snover is the way to go. It gets decent defenses with Eviolite, has access to Leech Seed and Giga Drain, and doesnt have the worst typing in the world. That being said, it can be great on offensive and defensive Hail teams, whittling down opponents with Leech Seed and Hail damage, and possibly a Blizzard/Giga Drain here and there, allowing for easier ohkos after the prior whittling. And this is especialy good on defensive teams to force switches. You said it wasn't too good with eviolite, but I believe it's very viable.
Snover @ Eviolite
Trait: Snow Warning
EVs: 248 HP / 160 SDef / 100 Def (or an ev spread of 248 hp/ 252 SpD/ 8 SpA with a Calm nature)
- Leech Seed
- Substitute/ Grasswhistle
- Blizzard/Giga Drain
Basically accomplishes what I just said. Can easily come in on Alomomola : p
Neverwinternights. Ill post more in depth later, it's too early to think right now. Add Kadabra though.
Edit: If Hail becomes a major thing, which it might, it would mean that Emboar and Sawk + Ice Types will be a lot more popular. So, Lampent is an interesting idea, but still can't do much.
