I’ve played a handful of card games I think about when I’m not playing. They’re good enough to roll around in my head even when I’m not at the table. Apocrypha, Netrunner, and Arkham Horror come to mind. But they’re all physical tabletop games, and none of them is the usual head-to-head card battle. Yet Mythgard, an online free-to-play game squarely in the tradition of the 1958 Richard Garfield classic that started it all, has found a place alongside them.
