Magcargo

Magcargo is usually relegated to NU due to its many shortcomings as a defensive Pokemon, mostly courtesy of its typing. Weaknesses to Stealth Rock and extremely common attacking types such as Water and Ground, an underwhelming set of resistances, and a rather paltry HP stat mean the poor snail doesn't see daylight too often. However, with good all-around defensive stats, a surprisingly good support movepool, and an alternative Rock-typing that serves it well when countering some of the most prominent threats in the UU metagame, Magcargo finds itself in an interesting niche.
