Magneton

Magneton is mostly outclassed by its evolution, as Magnezone has superior offensive and defensive power, but Magneton's niche lies in its higher Speed, which allows it to outspeed Pokemon such as Weavile, Starmie, Tornadus-T, and Jolly Talonflame when equipped with a Choice Scarf. Magneton has a very good Special Attack stat that allows it to hit quite hard. It has a good ability in Magnet Pull, which allows Magneton to trap and beat Steel-types. It can use Volt Switch to help keep up momentum for teams. Magneton is immune to paralysis and poison, which allows it to absorb these sorts of status for teammates. It has a decent Electric / Steel typing, though it does have a 4x weakness to Ground-type attacks. Magneton has average defenses, but those are a bit let down by a mediocre HP stat. It has a small movepool with very limited options, which allows it to only fill out a single role effectively. Magneton is also easily beaten by specially defensive Pokemon, though it is capable of switching out against all Pokemon but Ground-types with Volt Switch. It is also rather item-reliant, as without its item, it will be too slow to outspeed several threats.
