While Avalugg and Hisuian Avalugg may not pose a significant threat in the current PvE meta, their ability to function as effective ice-type attackers is undeniable. While they’re relatively bulky, this bulkiness makes them well-suited for anchoring themselves in gyms and withstanding the impact of incoming attacks.
