I looked at the companion match tracker, specifically Commander. I was confused by the tax feature, the damage feature, and the counters. Also, there was only one page where I saw a reset or clear all. And the mana counter seemed simple, but why?

One other thing: each player should have a phase indicator similar to Arena, which would turn on after a player hits “End turn”. Hmm; maybe start with the “End turn” button which indicates the active player
