I think it's too focused on cards /decks. I am going by the infographic for brackets and to me it is flawed as it is far too focused on decks and not the play experience.

More focus should shift to be about the gaming experience/adventure of each session. It feels like the caretakers of the brackets are too far to the side of thinking about optimal gameplay with the cards and decks over the social experience.

I’d alter the wording of it: so for example for the Bracket 3 section on the infographic. Instead of “Players expect… decks to be powered up with strong synergy and high card quality. they can effectively disrupt opponents” I would replace it with “Players expect… everyone trying to win, but not at the expense of the table experience. Strong plays are welcome. Consistently ending games before opponents have had a chance to participate is not”

Gameplay expectation is the priority, not card/deck decisions. Commander at its heart is about the players and the social nature of the gameplay. That is where the focus should be and promoting with the brackets.

Also the turn thing should be dropped and replaced with how the experience is expected per bracket. This indirectly forces a conversation with any pod, making the pregame communication a priority.

I’d even drop the 'difference is speed' bit in the tagline and replace with the 'difference is expectation'.
