Sableye

Sableye is a well-rounded defensive Pokemon in the PU metagame thanks to its good typing, solid utility, and access to Prankster. Sableye's Ghost / Dark typing not only gives it good immunities to a lot of moves while leaving it only weak to Fairy but also makes it a capable spinblocker. Prankster gives Sableye's status moves priority, which is a nuisance for the majority of the tier, as priority Taunt and Will-O-Wisp can really mess with a lot of Pokemon that want to set up, heal, or simply attack. Access to priority Recover also makes Sableye a durable and consistent wall. Unfortunately, poor base stats make Sableye fairly vulnerable to strong wallbreakers. It also means Sableye is reliant on Will-O-Wisp to check a lot of physical threats, even with physical bulk investment. Additionally, status moves affected by Prankster have no effect on opposing Dark-type Pokemon, so they usually can switch into Sableye freely and pressure it out. Finally, Sableye is vulnerable to strong special attackers especially when uninvested, which means it does still require some support to function effectively.
