Celesteela

Celesteela's typing and defensive stats are both fantastic in UU, allowing it to check a considerable portion of UU's top threats, including Salamence, Scizor, Diggersby, Hippowdon, Nihilego, and Excadrill. Thanks to its decent offensive stats, powerful STAB Heavy Slam, and access to Flamethrower to smack foes like Amoonguss and Zarude, Celesteela can prevent itself from being too passive. Leech Seed is also an excellent tool, sustaining Celesteela's longevity and allowing it to significantly wear down its switch-ins, such as Rotom-H and Thundurus-T, potentially forcing them out, while Toxic lures and cripples otherwise safe switch-ins like Rotom-W, Slowking, and Moltres. Celesteela can also operate with an Autotomize set, tapping into its strong special coverage and the sweeping potential Beast Boost lends it to clean through many unprepared teams. Despite its defensive potency, however, Celesteela suffers a bit from its lack of access to reliable recovery, which can prevent it from tanking strong neutral hits as consistently as it would like to and cause it to be overreliant on Leftovers. This can allow a few common Pokemon, such as Hydreigon and Mamoswine, to muscle past Celesteela after relatively minimal chip damage. Celesteela also struggles to bypass popular Fire- and Electric-types such as Moltres and Thundurus-T on its own, as well as various defensive picks like Tentacruel and Slowking; Tentacruel can utilize Liquid Ooze to take advantage of Leech Seed, while Slowking doesn't take meaningful damage from any of Celesteela's attacks, can absorb Leech Seed and Teleport out, and can threaten to chip Celesteela down with burns from Scald.
