I keep all my commanders in toploaders because I have them in my MTG Commander / EDH Deckbox with Showcase. That's why I made this standing command zone that holds up to two toploaders.

Track commander tax (+partner)

Keep track of your commander tax for both your command and their partner.

3 trackers up to 99

You can use the three extra counters to keep track of anything you like: commander damage, life, unspent mana, treasures, clues. You name it.

Vertical commander

The commanders are held in a vertical position to limit the amount of used board space and to make clear that the commander isn't in play.

Fully printed

The command zone is fully printed. No extra parts or glue required. You may need to apply significant force turn the printed screws during assembly. I recommend you use some grippy material like the rubber of your playmat to get some purchase on the screws.

If you would like to see any adaptations, let me know in the comments!
