There’s a Gym Leader help thread that can offer some good suggestions if you give them your team. Or you can make a separate thread too to get advice. 
 

In the meantime (it’s been a while since I last challenged her), I remember Klingklang’s Mirror Shot (as well as solid defences and great typing) tearing through her team, wrecking three mons on its own.
 

If you care only about winning, you can also destroy her field with a Pokemon knowing Earthquake (Donphan, Krokodile, Swampert) or Boomburst (Noivern) or any other way. Losing her field doesn’t make her a pushover but it usually helps. 

To name a few, Klinklang from the railnet, Vanilluxe from the ice cream machine at obsidia ward, and escavalier. Pretty much every steel type pokemon you can get (or pokemon with mirror shot/nature power) can do well against her whole team

I beat her! thank u!!
