This design is based off of the concept by Zeiphon on Thingiverse.
The idea here is you keep your unused tokens somewhat hidden, keep the spent ones out in the open, and secretly choose your tactic, place it under the cap and reveal.
I had a lot of trouble with the wonky existing tokens that come with the game. This was a great idea and something that I vastly prefer.
Another thought could be printing two caps – keeping one on your unused chips in a stack to hide the top one, and using the other as normal.
