Snover

Snover is one of the best hail setters due to its ability Snow Warning automatically setting it upon switching in. Alongside the hail support it provides, it has a good synergy with Alolan Sandshrew, which benefits from the hail. Snover also has access to powerful moves such as Blizzard, which has perfect accuracy in hail and can do massive damage; Giga Drain, which does reasonable STAB damage and provides a form of recovery; and Ice Shard, which can clean off weakened Pokemon. With a Choice Scarf, Snover can outspeed almost all of the unboosted metagame and take out a variety of different Pokemon such as Water-, Ground-, and Flying-types. Snover's Grass / Ice typing leaves it very weak to the common Fighting-type Pokemon and Stealth Rock and the majority of its setters. Snover also faces competition from the two other hail setters, Alolan Vulpix and Amaura, which can set up Aurora Veil and Stealth Rock, respectively. However, Snover differences itself from the other two hail setters due to being able to recover health with Giga Drain, and it can also clean weakened Pokemon with priority moves as well, which are traits that Amaura and Alolan Vulpix don't have. Snover may have Hidden Power Ground, but it mostly cannot KO its checks in a one-on-one situation unless it hits them on an expected switch, so it lacks reliable coverage.
