Magnezone

Magnezone's main draw is trapping and removing Steel-types such as Corviknight, Skarmory, and Ferrothorn with Magnet Pull. This support greatly enables many of the strongest sweepers and wallbreakers in the tier, such as Garchomp and Rillaboom. Its coverage is limited but effective, with different options to trap additional foes. However, Magnezone is held back offensively due to its low base Speed, leaving it revenge killed by the many faster Pokemon with super effective coverage. Its lack of longevity is also fairly limiting, denying it a defensive niche despite its great defensive typing. Further, Magnezone can't trap all relevant Steel-types with one set, forcing it to pick certain targets to trap.
