Giving no score for the AI matchs is not the best idea. It's a good idea, securly grounded, but still, zero score for beating the false gods? We can have the score scale down as we fight with the AI more, until it reachs either zero or another like-wise low point, and you could revive gaining score from AI by fighting a match in PvP, but seriously, play 1,000 games against AI while building your deck because of how unbalanced and buggy PvP is and getting no score. That's just a bit much for me. Besides, grinders are better than hackers.
