Steamforged Games surprise cancelled further production of the tabletop game Guild Ball in a statement they have since deleted from their website that said they made the perfect game, but the game was being played wrong by the players, whose fault it was that gameplay and the meta was becoming risk-averse and stagnant.

I’ve seen using mpcfill.com to make your list of desired cards, and then using the built in export over to makeplayingcards.com.

About proxy legality, outside of sanctioned events even Wizards is cool with proxies (they refer to them as playtest cards, not to be confused with actual playtest cards created during development) existing, so long as they are different enough from real cards they can’t be considered fakes (typically done with either a different backing or adding some text to the bottom) and retailers don’t make products for sale using the copyright symbols (colors, tap/untap) without permission.

I played the demo, was solidly fun, it’s on my list, but I’m still on StS2 atm.
