I played for about an hour, and the game is really good.
A couple of things I'd suggest to help reduce the text-heavy feel: maybe put the stats like damage, spells, and block directly on the cards themselves to make it feel more polished. By that, I mean using a clear number and an icon (like a number next to a sword), rather than relying so much on text.
Also, adding some graphics settings would be great so the game runs smoothly on both low and high-end systems. (I was playing on my phone while away from home, and it was a bit laggy.)
Overall, it's really well done; it plays smoothly and looks great. The only other adjustment I'd suggest is making the CPU playthroughs more varied. Right now, it feels like they tend to pull the same cards and use the same style, so mixing up their strategies would make matches feel a lot better.
