I am not anymore, though.
I made my first white Magic Deck. It's a combo of Clerics, Soldiers, and Life Boosters. Took me a while to whittle it down to less than 100 cards because I have so many good cards, though. Anyway, now that this is done, I can battle with another deck.
Once I get that Blue deck out of the way, I'll be pretty much set for most battles. However, I don't think I'll get to the Blue deck any time soon.
