We always had trouble in my group keeping track of commander damage, "How much did my commander deal to you last time?", "Is it 21 damage with this attack?", "You have 9 poison, and I proliferate", "WAIT! I'm pretty sure I only have 8 poison", and so on...
This tracker helps keep track of each players life total and commander damage. You can also use it for Brawl games and classic 1vs1 20 life games.
No ads or any annoying "in your face" features!
"Why can commander damage go over 21? Or life into negative numbers?" - Some people like their platimun angels with hexproof and whatnot.
