IVs: 0 Atk
- Nasty Plot
- Shadow Ball
- Dazzling Gleam / Hidden Power [Fighting]
- Taunt / Will-O-WIsp
Additional Moves: Thunder Wave, Toxic

Notes:
-Foul Play is used to hit Stoutland and Guts Ursaring for good damage, who otherwise switch into Misdreavus safely.
-Memento should be used when Misdreavus is paired with setup sweepers such as Swords Dance Ursaring, Speed Boost Combusken, and DD Torterra. Taunt usually offers better utility, shutting down passive Pokemon and preventing hazards from being put up. 
-Misdreavus can run Thunder Wave over Will-O-Wisp for speed control or Toxic to better deal with Normal-types such as Vigoroth, Bouffalant, and Lickilicky.
-A Timid Nature can be used over Modest on the Nasty Plot set to outpace Servine, Jolly Monferno, and Gabite.
-Dazzling Gleam is the preferred coverage move, hitting Dark-types and Fighting-types such as Vullaby, Shiftry, Poliwrath, Hakamo-o for super-effective damage. Hidden Power [Fighting] can be used to nail Probopass and Pawniard, as well as giving Misdreavus the ability to hit Bouffalant and Vigoroth for good damage after a Nasty Plot.
