Hippowdon

Hippowdon is an extremely potent mixed wall in UU thanks to its amazing bulk, solid typing, and reliable recovery. Its naturally high Defense allows it to invest in Special Defense to check Salamence and Thundurus-T while still answering physical attackers like Excadrill, Zygarde-10%, and Cobalion. Its bulk even lets it trade with threats that hit it super effectively like Tangrowth and Rotom-W and cripple them with Toxic. Hippowdon is a great Stealth Rock setter due to matching up well against common entry hazard removers like Salamence, Mandibuzz, Excadrill, and Tentacruel and easily setting Stealth Rock against Pokemon it walls like Excadrill, Cobalion, and Nihilego without Grass Knot. Utility options, like Toxic to cripple Tangrowth and Rotom-W and Whirlwind to keep setup sweepers like Scizor from setting up on it, limit Hippowdon's passivity. However, Hippowdon is still quite passive, relying on Toxic to cripple the common Grass- and Water-types that beat it; even then, threats like Zarude and RestTalk Primarina don't mind it. Certain setup sweepers like Bulky Swords Dance Scizor and Autotomize Celesteela can use Hippowdon as a free entry point, as well as setup fodder if it forgoes Whirlwind, which usually happens due to Toxic being very difficult to drop. Even Pokemon Hippowdon should check, like Nihilego, Thundurus-T, Rotom-H, and Moltres, can get around it by using coverage moves like Grass Knot or crippling it with Toxic.
