Linoone

Linoone is truly a blessed Pokemon. What would otherwise be a run-of-the-mill, throwaway Normal-type rodent along the likes of Raticate and Furret has access to a one-turn, game-ending sweep setup. Belly Drum turns the mild-mannered mustelid into a pillar of hellfire, a screaming Harrier jet, a towering tornado of fury wielding 1048 Attack, 405 Speed, and an 80 Base Power, STAB priority attack. Packing Linoone gives you a deadly secret weapon for when your enemy shows a moment of weakness, and once its presence is known, Linoone becomes a powerful psychological threat that will have your opponent on his toes the entire match. Adding in team support makes Linoone a fairly reliable late-game sweeper. If you have an opportunistic, high-risk high-reward playstyle, Linoone may be for you.

Beware, however, that Linoone is extremely frail and unforgiving; improper scouting, or a single mistake in prediction, will quickly turn Linoone into a dead weight.
