Avalugg

Avalugg is the best Rapid Spin user on Ice-type teams because of its physical bulk and reliable recovery in Recover, which enable it to take most physical attacks with ease. On top of this, it has an above average Attack stat, meaning it typically isn't setup bait. It also has a great ability in Sturdy along with access to Roar, which allows it to almost always phaze setup sweepers such as Mega Scizor and Volcarona if at full HP. However, Avalugg has a terrible Special Defense stat, which leaves it susceptible to special attackers such as Mega Charizard Y and Tapu Koko. It is also weak to common Fire-, Rock-, and Fighting-type attacks, which hinders its longevity in battle and makes it much harder to remove entry hazards. Avalugg is also extremely slow, even for a defensive Pokemon, and is outsped by the entire metagame, meaning it often needs to take a hit before attacking and is susceptible to Taunt users such as Smeargle and Gyarados. Avalugg is also weak to Stealth Rock, which makes its job of removing hazards extremely difficult.
