Quick question: do you have the rights to use Wizards of the Coasts/Magic the Gatherings copyrighted material?
Very good question and the very first problem we had to solve time ago.
It's easy though: there is only a way not to infringe copyright: releasing software without Images and Automated Rules. CGC Project is a "game engine" not a "game", CGC Project provide a container and its operative manual. We can't be held responsible if you download card images of a copyrighted game, we can legally replicate subcontainers (card boosters, collections), card text but no flavour text, turns/phases, if we do not use cards images inside the container itself.
We did not invented anything new in this kind of copyright management, we did researches about it: other people faced similar problem, even online 1player decktesting tools developers. About time we write a nice disclaimer about the copyright issue, thanks for your suggestion, it's been really useful and appreciated!
P.s.
Don't worry, I'd bet some user will be kind enough to offer complete full images repositories, for Both HD and SD versions, even before public release. Someone may turn "Rules" on as soon as we migrate to blockchain environment for the same reason.. We can't promote the download of anything related, you can understand..
