yeah i'm starting to notice the cards aren't too hard to get. if you focus your deck for a specific function i.e fire then sell some of your various cards and get what you need and as your deck is focused just spend some time on level 1 and get cards. i won multiple stuff like a stone dragon and sold it lol to get a time egg which is much better XD
It seems the creator of this was actually just doing it for a contest O_o and felt like he would release it. So i guess he or she can definetly improve it. Hence the director's cut
