Hattrem

Thanks to Magic Bounce, Hattrem can deter entry hazard setters, an incredibly valuable niche due to the tier's lack of hazard removal options. It also has quite a solid offensive presence, bringing a solid Special Attack stat and good coverage options. Hattrem's utility movepool is very deep too, with good options such as Aromatherapy, Healing Wish, and Nuzzle. Furthermore, it has quite decent bulk with Eviolite and can check threats like Garbodor, Sandaconda, and Regirock. However, it's very susceptible to getting worn down over time, and it's threatened by a lot of common Pokemon in the tier, such as Jellicent and Sneasel. Furthermore, against entry hazard setters like Sandslash, Aggron, and Palossand, it can struggle to deny hazards, making it obsolete in certain matchups.
