I was doing double battles in Stark Mountain. I had an illuminate lead instead of my damp lead. I switched into my damp Pokemon, knocked out the Claydol, and fainted the non shiny opposing Pokemon. However, Graveler used double edge on the same turn that I fainted the opposing Pokemon. It took recoil and fainted. The opposing Pokemon and Claydol had done enough chip damage to make the recoil kill itself.
