Guys, stop complaining about the difficulty, because imo it is just right. All the difficulties up to hard are not too challenging (i beat hard mode without too much of a challenge, beat boss on my first try, and no it wasn't luck). you just got to learn the mechanics and inside out of armor and know what to equip at the right times. I haven't beaten epic mode yet, but there's a reason why it's called "epic". Just because you can't beat a boss level doesn't mean the game sucks and deserves a 1/5. Personally, i think this game deserves a 1337/5. Press + if you agree.
with the deck i used (which i'm sure is not the best-- i just put it together rather sloppily), which consists of all building cards and recruit cards, the hard campaign seemed not too difficult. usually, if i didn't get about 2 recruit cards in the first 2 turns, then i just restarted, but those were rare occurences. the times that i didn't restart, i lost only twice, and won the other 8 (?) times. it took me about 30 minutes max to win the campaign
