This is a really good concept, it definitely needs more work on the balancing as well as UI. Tutorial needs more work as well. Maybe a tutorial battle. Plus enemies are very annoying, they just melt my HP and they don't take damage. Enemies use their abilities every turn while I am sitting on a cooldown. Merging doesn't work at the start and the shop cards that I got were basic trash. Cards with only healing abilities and cards with huge cooldowns. I might be playing the game wrong I think. Anyways great idea, I can see it going somewhere if you work on balancing and UI a little bit.
