There are so many exciting and interesting commanders in the format but some of them end up being unenjoyable once you play games with them. However, build any commander you want! This is just some types of commanders I personally try to avoid when I'm brewing a new EDH deck. I prefer decks that myself and others would want to see played again in the future. Have you ever built a commander deck that was received poorly by your others? Have you built a commander only to realize that it was not enjoyable for yourself?
