What Snow Warning does for the team
Harsh snow gives every Ice-type Pokémon on your side a 50% Defense boost, making them significantly harder to KO with physical hits. BlizzardBlizzardmove110 base power Ice-type spread move. 70% accuracy normally, but always hits in Snow weather. The signature offensive move on Snow teams.Click to read more →, normally only 70% accurate, becomes a guaranteed hit — and as a spread move it hits both opposing Pokémon simultaneously.
Unlike rain or sun, Snow doesn’t boost or cut a specific damage type globally. The advantage is defensive bulk and Blizzard consistency rather than raw offensive multipliers. Teams built around Mega Froslass lean into Ice-type attackers that appreciate the defensive buffer and the high-powered spread move.
Ghost typing
Ice/Ghost is a threatening offensive combination. Ghost-type moves hit Psychic and Ghost types that would otherwise wall Ice attackers. The Ghost typing also gives Froslass an immunity to Normal and Fighting moves — two of the most common physical attack types — making it surprisingly hard to revenge kill without a dedicated counter.
Why it’s winning
Froslass’s edge comes from the combination of instant weather, strong offensive typing, and the defensive buffer Snow provides to the whole team. Snow teams have been underrepresented in early Reg M-A testing, meaning opponents often don’t have Snow counterplay prepared.
Counters
- Overwriting the weather — Pelipper (Rain), Torkoal (Sun), or Tyranitar (Sand) switching in replaces Snow immediately.
- Steel-type moves — Steel resists both Ice and is immune to Poison. Steel-types generally take little from Froslass’s coverage.
- Fire-type moves — Hit Froslass for 2× damage and aren’t mitigated by Snow.
