It in the previous fight OHKO all my Pokemon with one of these attack (except Inteleon with Wacan Berry). I have a two ideas how to beat it:
Nr. 1 - Rapidash with High Horsepower, 252 Attack
Nr. 2 - Choice Band 252 Attack Excadrill with Earthquake, she will use Dig and excadrill will inflict double damage
If you know another way to beat it, please, write it
