This is a super cool game!
At first I didn't realize that my opponent had the same cards as me until I read the comments. After I realized that the game became much more interesting.
I think it'd be good if the modifier card was a toggle-able feature. Learning the basics can be a little difficult when the core rules are changing on you every round.
I love the art and animations. The game feels incredibly polished. I can tell you put a lot of work into this.
Awesome game, well done!
