Great art and mood, as always! The UX is especially polished, with a lot of juiciness for each actions.
I find the core mechanics really interesting. there's an interesting balance to find between spending magic, health, having more dices... However, too often I felt into (apparently) un-winnable situations. A bad hand of cards, either none that would grant me magic where I need it, or on the contrary when I have a lot of magic only cards that deal damage without healing, or several turns without having any dices, etc... This kind of game-design can be very tricky to balance! I was eventually able to survive for a while, but was for from being able to beat the game.
Which I regret a bit, because it is very fun to play! I don't know if it needs to be so much fast-paced. on one hand I loved the rush of the actions, and having to take decisions quickly. But on the other end I would often panic and feel like I'm stuck with only bad options. I still enjoyed it though, it has the potential to be a very solid card game. Good job!
