What it does on the ladder
Froslass appears on 0.03% of Regulation M-B teams, which
is 255th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Frost Breath, on 72.7% of sets.
The item is usually Wide Lens at 43.3%.
The ability is split: Cursed Body on 79.9% and Snow Cloak on 20.1%.
Those are Smogon's published usage figures, not anything measured here, and they describe what
the ladder plays rather than what is strongest. The full set is in the panel above.
The Pokémon itself
Froslass is number 478 in the National Dex, a Sinnoh Pokémon, Ice and Ghost
with a base stat total of 480 — 187th of the 234 Pokémon
legal in this regulation. Its best stat is Speed at 110, 25th
in the format; its weakest is Sp. Def at 70, 174th.
It can have Snow Cloak and Cursed Body.
The Champions module tiers it UU.
It sits in a 2-stage line: Snorunt → Froslass.
Not all of that line is legal in this regulation — Snorunt is not.
What gets through
As Ice and Ghost, 5 of the eighteen attacking types do extra damage to it. It
resists 3 and is immune to 2. The board above
has all of it. No other legal Pokémon has this typing.
What threatens it
Smogon publishes no head-to-head checks-and-counters data for doubles formats, so this list is
computed, not measured: the most-played Regulation M-B Pokémon carrying a damaging
move of a type Froslass takes extra damage from.
- Kingambit — Sucker Punch (Dark, ×2), on 99.8% of its sets
- Incineroar — Flare Blitz (Fire, ×2), on 91.2% of its sets
- Garchomp — Rock Slide (Rock, ×2), on 75.9% of its sets
- Charizard-Mega-Y — Heat Wave (Fire, ×2), on 99.2% of its sets
- Basculegion — Last Respects (Ghost, ×2), on 99.9% of its sets
- Archaludon — Flash Cannon (Steel, ×2), on 94.9% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Froslass reaches
178 Speed; left uninvested with a neutral nature it sits at
130. Invested, it outruns 15 of the 20
most-used Pokémon in the regulation when they are invested too — which is the comparison that
decides who moves first.
It weighs 26.6 kg, so Grass Knot and Low Kick hit it for 60 base
power. That is a real consideration in a format where both are common.
Its move pool
Froslass learns 100 moves in the Champions data.
48 of them do damage, across 13 of the eighteen
types, and 19 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Blizzard at 110 base power, though the biggest number in the pool is Giga Impact at 150.
It also has priority: Sucker Punch at +1 and Ice Shard at +1.
That pool is what the team builder reads from when you seat it, and the
damage calculator will take it as the attacker with
the form already chosen.
