Thanks for playing and for your comment, friend!
A tutorial is definitely needed, I've been evading making it for a while, but it will be done soon enough.
The art will be replaced at some point and hopefully it will be better than the current placeholder AI art, but I'm happy to hear it kinda worked for you.
The champion not playing anything is due to each deck being randomly generated, they probably got a really bad deck with not enough cheap cards. However this is less of problem the higher you go on the difficulty ladder since enemies get stronger and their decks do so as well.
Again, thanks for the feedback and for your time!
