I'm not huge on card games but this is one of the best mobile game in terms of actual quality and playability. This is an actual game and not a mobile addiction simulator. I've lowered the rating one star With the removal of lab of legends and addition of path of champions, the slay-the-spire-esque single player mode has been greatly expanded, but at a price. The mode is now harder, more grindy, less accessible, more punishing, and less open ended.
