Great game! I love the aspect of enemies getting upgrades when you do! I like how you make it so that you not only have to focus on your synergies, but you have to worry about the enemy's synergies as well! You should absolutely add a reload button though.
It used to work on mobile a few weeks ago on web, now it just crashes(webgl error or something.) I dont know what happened, but this would be a lovely mobile game.
The card has so many synergies, and it's a "Pick Always" card for me. I think it should be a legendary card, singe it works so well with "When you draw" cards.
