Magnemite

Due to Magnemite's amazing Steel typing, high Special Attack, and difficult-to-resist STAB Thunder, it can make for an excellent long-term defensive answer to Xatu and Fearow that's capable of repeatedly switching in on them to fire off attacks, battering away at the opposing team. On the surface, Magnemite may seem difficult to justify over its fellow Electric-type, Chinchou, which is much faster, has STAB-boosted Surf, and resists Water, allowing it to switch into Octillery and Dewgong unlike Magnemite with its low Special Defense. The primary reason for Magnemite's use is that it is arguably one of the best answers to Xatu and Fearow, two of the strongest and most dangerous offensive forces in the tier; it also answers Persian remarkably well. However, Magnemite is plagued by common Pokemon that take advantage of its weaknesses, such as Ninetales, Rapidash, Dugtrio, and Primeape. Magnemite isn't completely helpless against these threats, though, as Thunder paralysis is extremely crippling and Dugtrio does not want to repeatedly switch into Magnemite in fear of Hidden Power Ice. However, Magnemite has some severely crippling and unavoidable issues, namely Thunder's poor 70% accuracy and often being forced into predicting what the right move to use is, such as whether to use Thunder on the Octillery right in front of it or Hidden Power Ice to hit the Dugtrio that may come in.
