Mamoswine (hgss4-5) is a Water-type Stage 2 Pokémon from the HS—Triumphant set with Rare Holo rarity. Its Icy Wind attack for three energy puts the Defending Pokémon to Sleep and its Snowstorm attack for four energy deals 70 damage and also deals 20 damage to each of the opponent's Benched Pokémon that already has damage counters. It has a ×2 weakness to Metal and a four Colorless retreat cost, making it a high-cost physical attacker with disruptive bench-targeting.
