A lot of fun, like the concepts and the gameplay loop!

(Though I do feel it could use some balancing tweaks - I managed to get my deck to be 3 freeze cards in my hand, 2 "Next attack bounces", the piercing quad-shot, and the free 2-shot cards, which allowed me to spam-freeze (and free-attack) to my hearts content, then when I wanted to kill enemies, I'd just wait, freeze, shoot a bouncing-piercing-quad shot to wipe the board, and repeat. I could've done so indefinitely if I wanted!)
