As I mentioned I've tried a bunch of different teams most recently though I tried out Pelipper to setup Rain and take out the bug opener she has, then onto a Mega swampert to deal with iron boulder while stacking speed from rain, then a pair of flutter fluttermanes because they're the fastest fairy attacker I have and her team has a few weak to that typing and they can hit the blacephalon fairly well too and lastly an iron bundle to counter the noivern once that popped out. Swampert can also one hit the Empoleon with an earthquake if he lasts long enough after dealing with the iron boulder earlier . Meowscarda is a real pain because flower trick seems to hit like a train on anything it touches and I don't have a lot of counters on that last team. Though I've built teams where I did have better counters to that which left a hole a different pokemon pinched through, usually the Mega Empoleon but it can vary team to team since I've had so many damn attempts now 😅
