Sableye

With the introduction of BW, Sableye was blessed with an incredible ability: Prankster. With no weaknesses, its excellent typing makes it deceptively bulky and easy to fit on any team. Its typing also grants it immunities to Fighting-, Psychic-, and Normal-type attacks. Sableye is the only Prankster Pokemon that has access to Will-O-Wisp, allowing it to shut down offensive threats before they get a chance to attack; it also has access to a wide variety of support moves such as Trick, Recover, and Taunt. Offensively, Sableye learns Sucker Punch, which can 2HKO several common Psychic- and Ghost-types, such as Latios and Chandelure, even with no investment in Attack. However, Sableye also suffers from many issues. Will-O-Wisp, its main move, has shaky accuracy and a miss can spell disaster. To make matters worse, Sableye also has poor defensive stats and cannot take too many hits. Specially based Pokemon that are not weak to Sucker Punch, such as Zapdos and Abomasnow, do not care about being burned, and can wall Sableye with ease. Nonetheless, although Sableye suffers from several problems, it is still an excellent addition to any team with its unique typing and movepool.
