Not that this is a complicated game, but I often find when teaching it that new players struggle with the order of operations and what the resources are called. And as smooth as the game is, we all forget what to start with, and a few of the fiddly rules (El Zorro & Alonso, etc.) that don't come into play very often.
This is four 2-sided cards on a single full-color sheet. The cards measure 3.5" x 2.5", when folded back-to-back (if you are a sleever.) Since the file is a PDF, I recommend printing it with "Page Scaling/Fit to Page" settings set to NONE/OFF (unless you want it to come out smaller--it's the difference between Fantasy Flight Sleeves & MayDay Sleeves.)
