That's strange. I was underwhelmed. The particular Drifblim I am talking about is:

819 | Drifblim | Bold | Custap Berry | Shadow Ball | Thunderbolt | Hypnosis | Destiny Bond | Spd/SpD

It does have max SpD (I was afraid of that), so that could explain why it was tricky. If I did my calculation right on the Smogon calculator, my Scarf Chandelure's Shadow Ball did 79.8% - 94.3% to that Drifblim. Maybe you haven't run into this guy yet :/

Honestly you should think about some of the changes I am suggesting:
1)Lead with ferrothorn. Give him stealth rock. Remove t-wave, since your team doesn't need it. I would suggest starting with a pokemon who has few weaknesses, so that you are not forced out again.
2)DONT USE chandelure as a sweeper. Use him as a revenge killer and a pokemon who can absorb the fire, fighting attacks thrown towards ferrothorn.(My chandy also takes down annoying pokemon like Frosslass and weavile which plague my Garchomp.)
If you want a sweeper, go with specs chandelure. You will need to spread Paralysis though. Maybe Parashuffler D-nite?
3) Okay your chandelure does have problems with heatran. In that scenario you can consider Brick break for dragonite. Firstly fighting gives perfect coverage with dragon and it hits stuff like ttar and heatran harder. Secondly, all those problematic Steel types like Scizor, Skarmory and Foretress will be torched by Chandelure.
Consider Psychic or Energy ball for the last slot since Hp ground isn't the best attack to get locked into.
