The art and concept look great. My biggest disappointment/pet peeve is the gems system. Why the hell would I spend FORTY DOLLARS just to summon 10 cards? Free gems are completely pointless because you cant use them for summoning. A complete waste of grinding time just to find out I can't even summon cards without buying forty dollars worth of gems because the gems you buy don't all count as "paid" in the first place, so you end up having to spend more. A total scam.
