What it does on the ladder
Mamoswine appears on 2.9% of Regulation M-B teams, which
is 48th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Ice Shard, on 96.6% of sets.
The item is usually Focus Sash at 58.5%.
The ability is split: Oblivious on 96%, Thick Fat on 3.7% and Snow Cloak on 0.3%.
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
Mamoswine is number 473 in the National Dex, a Sinnoh Pokémon, Ice and Ground
with a base stat total of 530 — 34th of the 234 Pokémon
legal in this regulation. Its best stat is Attack at 130, 13th
in the format; its weakest is Sp. Def at 60, 207th.
It can have Oblivious, Snow Cloak and Thick Fat.
The Champions module tiers it UU.
It sits in a 3-stage line: Swinub → Piloswine → Mamoswine.
Not all of that line is legal in this regulation — Swinub and Piloswine are not.
What gets through
As Ice and Ground, 5 of the eighteen attacking types do extra damage to it. It
resists 1 and is immune to 1. 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 Mamoswine takes extra damage from.
- Kingambit — Iron Head (Steel, ×2), on 67.8% of its sets
- Incineroar — Flare Blitz (Fire, ×2), on 91.2% of its sets
- Charizard-Mega-Y — Heat Wave (Fire, ×2), on 99.2% of its sets
- Basculegion — Aqua Jet (Water, ×2), on 96.6% of its sets
- Sinistcha — Matcha Gotcha (Grass, ×2), on 97.9% of its sets
- Sneasler — Close Combat (Fighting, ×2), on 99.7% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Mamoswine reaches
145 Speed; left uninvested with a neutral nature it sits at
100. Invested, it outruns 10 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 291 kg, so Grass Knot and Low Kick hit it for 120 base
power. That is a real consideration in a format where both are common.
Its move pool
Mamoswine learns 91 moves in the Champions data.
54 of them do damage, across 10 of the eighteen
types, and 20 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: 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.
