Chandelure is more offensively geared, and it doesn't have room for it in its moveset.
You should use one of these Pokemon - Weezing, Garbodor, Amoonguss, Gastrodon, or possibly Drifblim - to use Clear Smog, as they are all fairly defensive. I recommend Gastrodon as it has two useful immunities, a fantastic HP stat, and not so so shabby defenses.
