See Kalejaye of the Nnikvi. Coffi of the Whiplash Hex was the hardest to figure out, since his ability was blended by the -1/-1 counters. I took a totally different route and tried to make him a more aggressive commander. Originally I wanted to give him first strike, but that felt a little redundant with his ability to prevent damage. I then considered vigilance, that still didn't feel too useful, since the damage prevention only happens during your turn. Then I decided, I'd go with menace from red's section of the color pie. It keeps Coffi an aggressive commander.
