I’ve made a couple things that I find helpful for Masks, and I thought I might share them here. One is a sheet of labels (long-term play tends to lead to erasing through the sheet, with label shifts), and the other is a sheet for tracking influence.

Addendum: the other two are for tracking influence. After I made the first sheet, I had an insight for a different (better?) way to do it.
