I'm sorry, UsernameLife, but I think your overall chance of winning isn't very high, especially against a Master who could use 6 upped cards. I would just make a deck that uses the least number of important cards, to minimize loss if you happen to lose. Right now my mind is pretty blank, and I can't really think of anything else, but I'll try again when I come back...
Wait... *punches self in face* We didn't take any Holy Lights...
