Super lovely game, I love to return to it with each update!
I have a few suggestions on the readability of the cards. Sometimes I don’t get the card's explanations. For example, I still don’t understand what the explosion wand does, it says that it deals extra damage in an explosion, but when I attack, it is still 3 — I’d think that the card explodes. Some enemies have something like "adds spikes to enemies when damaged," I was confused if I shouldn’t damage that card or other enemies. What could help is testing those out with other people to catch those difficult to understand wordings, we do this with art critique all the time! (or maybe it’s just me :p)
Another suggestion would be changing the shape of the letter "w" as it’s easy to confuse with "m," like in wands–hands. And as the typeface is pretty thick, if you add more space between the letters, they will be easier to read when small.
