The game is good, at least for PvE. The campaign has a few challenging parts to it, and the ability to get packs gold you earn is pretty damn cool, but the deck builder seems a little cluttered. It's still easy to navigate, and it's simple, but again it seems a little clutter.
Using no energy for PvE is also amazing, and lets us play for as long as we want without having to stop and come back. The art is pretty awesome in a cartoonish way. I got to say, this game is well made, but a few problems here and there won't stop me from giving it a 4/5.
