I really enjoyed the game. More little bits of feedback.
Late game gets really messy and I love it. I got around that by constantly pausing, lining up how I was going to move a card, then unpaused->moved card->paused again. This was especially important for larger fights as I would pause, then do the unpause->move->pause trick to make sure the enemy was fighting all of my warriors without delay.
It was fun figuring out how I could exploit the pause/unpause to optimize my time in the messy late game. But now I feel I may have "cheated" somewhat, like I was trying to turn this real-time game into a pseudo turn-based by staying in paused time so much.
Thanks again for a fun game! I hope you have time to add more little things and interactions!
