I'm enjoying the game quite a bit. It's been easy to keep coming back daily for the login in bonuses, but the time it takes for your energy to recharge is way too long. Now that my deck is more than substandard, and I'm slowly building themed decks, I'm starting to rip through energy really quick. Especially with the later story levels costing 9+ energy per attempt. It's pretty clear if you want to be any "good" you've gotta spend the dosh to get all the best cards.
