Lots of fun! I enjoy deckbuilders, and this was a nice simple one with good variety. Sound effects were decent, but I'd love to hear some music. If music isn't your thing, I recommend checking out #team-up next time for a musician. There are usually a good number of musicians willing to contribute, and that kind of contribution doesn't require nearly as much back-and-forth as some other contributions (e.g., art).
Room for improvement: text was really small, especially the health indicator. I would like a way to undo my last action. Sometimes I click something by accident. A visual indicator of the different ranges would also help: knowing the card gives me 2 movement is great, but if I don't know how far that is until I use the card, that's less useful.
