Never played TCGs, so it was an interesting experience. I can see why people enjoy it - once you kinda start understanding what's going on - it becomes pretty fun and addictive.
It works well enough, and crafting mechanic is really, really interesting. I think potion autoconsume saved me once.
I don't know what else to say, since, once again, I have no idea what are the staples for a TCG. It seems to be fairly well balanced, and I almost completed the entire run, which is great for me since I'm a complete novice. Though some tutorials for people not familiar with the TCG genre would've been nice.
I liked it. I think I'll try playing it again off-stream just to see what else is there, since I haven't played any other classes and haven't explored the hero progression outside of the game itself.
