Man, i love the move taunt especially on ghost types and Chandelure is no different. This set can stallbreak as well as the SubCM set can but instead of acting like a win con. it offers more utility such as badly poisoning Taunt Roost Hydreigon and limiting its job. Taunt also stops Empoleon to defog who likes to switch into specially after noticing leftovers. Because most normal types can't touch Chandelure in return (see standard Curselax, Blissey, P2 lacking thunderbolt) mono ghost has decent neutral coverage only missing out dark types. The last move is a filler and should be chosen depending on your teams needs. I personally prefer wisp since it can cripple Aero, Krook and other darks on the switch. It also allows you to beat SD Toxicroak safely. I like having max speed timid but one can use less speed or sp.att and invest in more HP.
Paired it with Umbreon because it can take on darks. Wish + Baton Pass keeps Chandy around reliably as Pain Split is a rather shaky healing method. Feel free to change moves or EVs just don't mess with the nickname of Chandelure as it cannot stallbreak as effectively without it.
