I was fighting Pryce's Dewgong with Togetis in the Mahogany Gym, and I used Metronome. The move selected was Rollout, and by this time, the Dewgong had used Encore. So instead of Rollout hitting my opponent, it kept rolling back at me instead. So in the end, I ended up0 KOing myself with Rollout. It was very strange. ;o
