Probably one of the best strategy deck building games or there just wish there were more to choose from as far as attributes, characters, and cards. 1player is challenging on all levels and winning is possible. Decent matchmaking engine. Shop is a little expensive for items and gaining currency is very slow for the grind. Like all deck games sometimes you don't get the cards you need while your opponent does. Some cards need to be nerfed or more card combos for the characters without like Zeacon
