I totally agree with your point on sash. It really is the better item since it allows Chandelure to beat things more effectively. I ran Tyranitar since it suits my playstyle a lot. So goggles was the better choice and improves Gardevoir/ Amoongus match ups.
Scrafty is annoying to deal with and so trying to fit a fairy on the team could be a good way to control it better. On to the point of Sucker Punch. Intimidate allows 252 hp Chandelure to survive 252+ Sucker Punch from Kangaskhan. So the prime user can not ko it if anyone wanted to know. I play with the idea that it can miss kos so chip damage is vital in allowing it to effectively do its job. Hence the spread damage on both prime users together.
Edit: Actually you should keep in mind that you could run Wide Guard Conkeldurr. Something which is making me think on additions I could adapt to my team. It might serve a better role if I do some switches. But I am thinking a Steel-Type just needs to be on since fairies just overwhelming even with large physical threats on the team such as Kangaskhan and AV Landorus-T.
I see. You could use a classic Specs Sylveon with quiet nature to add some spam preassure, or if you want somethin for more support you can try this:
Aromatisse (F) @ Safety Goggles
Ability: Aroma Veil
Level: 50
EVs: 252 HP / 220 Def / 36 SpD
Relaxed Nature
IVs: 0 Spe
- Trick Room
- Moonblast
- Heal Pulse
- Protect
another TR setter in cause the enemy matchup weren't favorabe to chandelure, like Rain Teams. Heal Pulse is really usefull, to bring back health especially if you run AV Landorus. If ou want a Steel type, aegislash is the most solid on the format, but having already a ghost ttype, probably the best option will be Scizor. Scizor brings priority move and you don't need to worry about TR since bullet punch goes fisrt too undesr tTrick Room. Also can make a good combo if you Sword Dance with Scizor and then Heal Pulse with Aromatisse.
