For the "Players" set, I'm missing three panels. I've put the CSV below, the rows with ?? are my guess at what they could be based on an image I reviewed of the table of contents for the associated book. I may end up buying the Players set, but if not, if someone comes across this looking to create the checklist in the future hopefully this will save them some typing.
