I remember reading an article about ten years ago, possibly on the mothership. It had some equations comparing how often a good player will beat a bad player, and how often a player with perfect information will beat a good player. It ended up concluding that aggro decks might take more skill to play than control decks. I haven’t been able to find it since, does anyone have a link to it?

Taking a guess.

I also found these which are in similar vein.

Thanks, it’s in the end part of the first one you linked
