Mamoswine

Sitting at 3.19% usage and rank 50 in singles, Mamoswine occupies the middle of the second tier. The Ice–Ground typing leaves nine weaknesses (Fire, Water, Grass, Fighting, and Steel all hit it for double damage) and grants only an Electric immunity, so its bulk does not hold up well against super effective coverage. It fills the role of a Stealth Rock setter and a priority Ice Shard attacker, but that role is crowded and it lacks a unique niche.

Playstyle：Focus Sash dominates at 85.1%, letting it survive a hit and retaliate with priority Ice Shard or fire off an Earthquake for maximum neutral damage. Oblivious at 79.7% mainly blocks Taunt, while Thick Fat at 20.3% is a minority pick that softens Ice and Fire hits. Adamant 252 Atk / 80 Spe (22%) is the standard offensive spread; Naughty 20.3% keeps the speed while investing in SpA to boost Freeze-Dry. Stealth Rock (7.1%) and Freeze-Dry (8%) are fringe options, but the former gives it a complete lead utility and the latter patches the Water matchup.

Doubles usage sits at 1.13% (rank 65), making Mamoswine a marginal pick. Ground-type Earthquake is a double-edged sword in doubles: the accuracy and spread damage are offset by the risk of hitting partners, which is why High Horsepower overtakes Earthquake as the most common Ground STAB (20.7%). Thick Fat falls to 5.7% and Snow Cloak to 2%, since the doubles metagame values Wide Lens-friendly ground moves over Heat-resisting ability slots.

Playstyle：In doubles Protect takes 22.8%, tied with Ice Shard at the top, which shows Mamoswine is used as a disposable screen or pivot. Life Orb at 39.8% is close behind Focus Sash at 47%, reflecting how little the format trusts its bulk. Adamant 252 Atk / 80 Spe is 40.3%, while Jolly variants at 20.3% and 10.2% together make up nearly a third, all built to outspeed under Scarf (5.5%) or to complement priority Ice Shard. High Horsepower's perfect accuracy plus Ice Shard's priority form the core loop, and Rock Slide at 7% adds the standard doubles spread control.
