Good teammates for Chandelure in Sword/Shield?

Question

What are good teammates for Chandelure for the battle stadium (Singles & Doubles) that cover its weaknesses and threaten its checks/counters? I'm mainly worried about Gyarados, Togekiss, Hydreigon, Dragapult, Tyranitar and Excadrill.

Please explain why said recommended teammates are effective.

I'm going to use a variety of sets. (Trick Room, Sub + Calm Mind, Will-o-Wisp + 3 Attacks, Choice)

Answer 1

Electric type teamates could lose to te grounds too, so I'd recommend Whimmscot. It can support with tailwind whilst attacking with Energy Ball, a move that will destroy ground, fire and rock types. If that wasn't enough, it's a Moonblaster, so bye dark types.

Hope I helped!
