This build is intended for use with a MegaSableye.
Will-O-Wisp allows Sableye to tank incredibly well despite meagre Def stats. Setting up confusion on enemies is both conducive to a tankier Sableye and just generally hilarious. With regard to confusion confuse ray is a safer play and better for most stalling, however swagger will allow for not only a far more hard hitting (generally OHKO) FoulPlay, but will make the confusion induced self damage to hurt the enemy more. But this comes at the cost of making the enemy more likely to inflict severe damage to Sableye if not affected by its confusion.
This is a good moveset for sableye (Pokemon #302) with the prankster ability/trait, a Impish nature, and equipped with Rocky Helmet submitted by Loken. For use in competitive Pokemon battles featuring an Export option and breeding guide.
