Chandelure

Chandelure is a powerful attacker that has the ability to act in a double-role. While it's not as amazing as it once was, it's still very much a worthwhile investment if you need help with Fire and/or Ghost damage output.

Best PvE Offensive Moveset

• Fire Spin pairs with Overheat to maximize Shadow Chandelure's performance as a Fire Type attacker and allow it to stand shoulder-to-shoulder with many of the game's top attackers within the type.
• Hex pairs with Shadow Ball to make Chandelure an outstanding Ghost Type attacker, standing as one of the best.
• Incinerate is notoriously slow and weaker than Fire Spin in practice generally speaking
• Flame Charge is a poor tool for an offensive Chandelure
• Energy Ball has no use on Chandelure, TM this. 
• Poltergeist* is an underwhelming option for Ghost Type damage. Stick with Shadow Ball.

Best PvE Defensive Moveset

• Incinerate hits hardest on defense and is the superior to Hex and Fire Spin. 
• Shadow Ball has the earliest damage window and also provides mostly neutral coverage. 
• Flame Charge is great for its low cost, allowing it to come out very often
• Energy Ball is the easiest to dodge and deals the least amount of damage, but also has counter-coverage against Water and Rock Types
• Overheat might not be used before Shadow Chandelure faints as a 1-bar move.
• Poltergeist* has the same issue as Overheat while simultaneously being out-performed by Shadow Ball. Skip this move. 

Incinerate is a powerful move in pvp, scoring large amounts of damage in short order. It pairs well with Flame Charge, which is a relatively spammable move, and Shadow Ball for hard-hitting damage.
