I wonder if it would be possible to do a CCG and have it be successful while being print-your-own. Maybe have it be a collaborative project where people submit art and cards to be considered for the next set, which releases every one or two months. The central group (and contributors) could even still make money by selling the cards - just instead of banking on artificial scarcity for profit they’d be running a print shop.

I think fans of Netrunner did this after the company stopped making sets
