Goldeen

Goldeen's ability Lightning Rod alongside its Water typing lets it handle several Electric-types such as Magnemite, Chinchou, and Elekid incredibly well. It's one of the best Volt Switch stoppers in the metagame; not only is it immune to Volt Switch, but it also resists many common coverage moves carried by Electric-types and can threaten them back with Drill Run. Goldeen also has a wide variety of coverage options to take advantage of its good Attack and Speed with, such as Knock Off, Poison Jab, and Megahorn. However, Goldeen is prone to being worn down quickly by entry hazards, Life Orb recoil, and switching into resisted hits, limiting its time on the battlefield. Despite this, Goldeen is still a fairly effective hard stop to Volt Switch users.
