ゆきかき (Slush Rush)

Slush Rush transforms Ice-type Pokemon into formidable speed threats when hail is active on the battlefield. When hailstorm conditions are present, Pokemon with this ability receive a full doubling of their Speed stat, potentially allowing even naturally slow Pokemon to outpace common threats and revenge kill opponents. This dramatic speed boost applies immediately when hail begins and remains active for the duration of the weather condition.

The ability underwent a notable change in Generation 9, where it now activates during snow conditions rather than traditional hail. This adjustment came alongside the broader weather system rework that replaced hail with snow in the latest generation. The mechanical effect remains identical, but the triggering condition shifted to align with the new weather mechanics.

Competitively, Slush Rush has found its niche primarily on dedicated hail teams, where Pokemon like Beartic and the Fossil Pokemon Arctozolt and Arctovish can leverage the speed boost to become dangerous sweepers. The newly introduced Cetitan also benefits significantly from this ability, transforming from a slow tank into a potential speed demon under the right conditions. The ability's effectiveness is inherently tied to weather support, making it most viable in team compositions built around maintaining consistent hail or snow conditions throughout the battle.
