Bronzong

Bronzong is an elite Steel-type in NU thanks to both its great mixed bulk and an excellent ability in Levitate, which, unlike other Steel-types, allows it to check many Ground-types like Flygon and Gligar, along with other Pokémon that rely on Ground-type coverage to hit Steel-types like Diancie. Bronzong is remarkably resistant to entry hazards, as it simultaneously resists Stealth Rock and has an immunity to Spikes, making it a centerpiece on teams with little to no hazard removal. Furthermore, Bronzong excels at being a great hazard setter thanks to its ability to check threats like Munkidori, Sylveon, and Porygon-Z. It can take advantage of these positive matchups and its already tremendous bulk by instead being a bulky setup sweeper, becoming very difficult to take out. However, Bronzong's only form of recovery is Leftovers, meaning that it has to be even more wary about switching into the already threatening Knock Off from Pokemon that it would check otherwise like Copperajah, Tsareena, and Toxicroak. Additionally, foes that Bronzong is typically expected to check like Munkidori, Florges, and Rotom-C often run Trick to cripple it severely and especially hurt its setup sets.
