Thanks for the tip! I do have Chandelure, but didn't find him that effective.
I think the problem is, using earthquake makes the field break, and whatever I do, their attacks always land (either night slash or something or flash cannon that uses the field...
I come out with noivern, fly mienshao that seemed to be the easiest way to take him down, then she takes out raichu then I earthquake with golem and then she always comes out with gallade and or lucario and it always strand there or after that, at the togekiss. never gotten further
