Really easy, if you cannto win in any way, get a Trapinch and destroy her. I did that with Skyla, her Swanna was just owning all of my Pokemon (Samurott, Flygon, Lucario, Arcanine). I had to get a Zebstrika and end the madness.
What is the level of the Pokemon near Dragonspiral Tower? I am planning on getting Beartic for my team, so yep... All my Pokemon are lvl 52-53 and I am in the 8th Gym.
