Yeah, there's a reason mine is Blue/White, so while I can do some Oath of Teferi/Chain Veil nonsense, plus a bit of proliferate or Clockspinning, I feel between that and using a powered-down Planeswalker deck planeswalker as my marquee it's more fun and fair (while still powerful, because blue/white).
Not that I place a whole lot of stock in their conclusions. I mean, I believe the math and trust the methodology they used, but my latest commander brew is a Boros deck (the color combination least likely to win according to their survey) packed full of board wipes (the sort of effect that makes the whole table hate you, according to my own experience).
Trust me. My playgroup deserves it. Commander is where we go full-on evil. If we want fair games then we'll draft something.
