I don't think you have much room (HA! Trick Room, like most Chandelures!) for Chandelure. It is a very good Pokémon, but many spread moves affect it badly. Imprison is a good move for doubles, but there are not many of those Pokémon now due to the fact Fire Gem has not been released. As well, most people tend to prefer Chandelures as Trick Room sweepers due to their unfortunate base 80 speed, thus making them struggle in both out and in the TR, since VGC is full of fast-butt Pokémon and slugs. As well, if you are playing in VGC, you'd rather use Heat Wave (lol flamethrower) as Overheat's base power has been reduced and still has that nasty negative effect. One of the few ways I see use for it now is a scarf or a sash, otherwise it won't be telling much in battle.
However, if you play it with its strenghts, it may be very good; ghost now hits steel for neutral and fire resists fairy, as well as having the classic immunities to fire, normal and fight. Just use it if you can support it very well with the moves you have used, but changing Imprison for another move and WoW for Trolltect if you are going with a sash or Energy Ball otherwise; you don't have time to burn many things in such a fast-paced game.
Regards.
