5 stars: Fun and free. I don't consider it a pay to win, as a free player can access all features... it just takes time. You get lots of ingame currency through daily challenges and competing in PvP. Lots of cards... too many to hope to ever get everything, and lotes of experience level to keep you going. The game is simple and can get repetitive... but it's great for casual players who want to play for 15 to 30min daily or once a month.
3 stars: Very cool deck building game with a nice trading system. The UI and menus need a lot of work to make the game easy to use and learn though. Seeing what cards and categories are connected to each other is one of the most frustrating chores I've had to do when just learning a new game. Please add a way to look at other cards and categories mentioned on cards in the collection. That will at least get 4 stars review.
