For Denro I'm gonna suggest Warrior, he had decent coverage, not the best but his KO's were from using the right attacks and not from crits or things like that. He didn't take advantage of items if I recall corectly, I think I used knock off on 2 of his battlers and I don't tihnk anything was taken either time. I was given ample time to set up entry hazards then move to the offensive when he couldn't risk a switch any longer
