I doubt the DM's Guild license would allow you to offer monster cards off the DM's Guild site, but . . . . OneBookShelf.com does offer POD playing cards, it might be possible to offer your own monster cards directly on the DM's Guild site.Thanks for the heads up. That's actually not a bad idea. Someone also reached out to me regarding 3d printed stuff. I'll reach out to DMG first about this and if they're ok with it, why not. I'll let you guys know.
