Why did this result in a tie?

Fought an opponent who just stalled the entire match with Night Bind and energy removal. I outsmarted them a bit and was able to get a KO by removing psychic energy from indeedee, turning on psychic terrain to switch out an indeedee at no retreat cost and then striking the taking out their first Banette with Porygon Z and changing their energy so they can't attack with Indeedee. It worked until they pulled Team Rocket Grunts and rolled an absurd amount of heads.

Still, I had a point and they didn't... Thought this would mean that if it's going to go to time then I'd win. Instead we tied? All that time wasted? Was my only options this match really just lose or tie because of the deck they're using???
