I love this game so far and am excited to see where it goes!
That being said, there are a few monsters that feel pretty overtuned in comparison to the rest of the roster. The nothisaur (I think that's how its spelled) makes me feel so helpless in the second phase with just how many poison hexes it puts in my deck. The red dragon simply deals way too much damage imo. Finally, the dragon golem resummoning its minions feels like too much.
Hopefully my criticism is constructive in the end. I do genuinely like this game and appreciate the time and care put into it. The mechanics and systems are overall well thought-out and engaging.
