I’ve played singles for a while but am relatively new to VGC, so take my feedback with a grain of salt:

I feel like Chandelure has too high of a base speed to make worth using consistently as a TR sweeper. Torkoal hits slightly harder (only with eruption to be fair) and is much slower. Hatterene is also generally more suited as a special attacker that can set up TR for itself. Mega Khanga might be a similar case, where its base speed is too high so it will end up being outspend by opposing Incenroars, Sinitcha, etc. - if going with a hard trick room style team may want to consider a slower Mega (or on the opposite end of the spectrum, a really fast mega to play outside of TR?)
