I've been dabbling in Faeria. It's an interesting CCG but I prefer Infinity Wars. Some of my complaints include: PvE experience offers no rewards, no rewards for losing games (no comeback mechanic), can't buy your draft deck, seriously favors aggro.
It is a fun game, and it has some awesome things going for it (daily quests, a crafting system, interesting board concept). Unfortunately, there's so much waiting involved when you're not playing with simultaneous turns. I'll probably continue to play Faeria casually, however.
