I Bought a couple of packs a week a long while back I think even before the tournaments started but havent bought any for a while and am not sure if I will, yes only one card at the lower level i think is hard and willlimit newcomers from getting into it,I think it would help it to grow if they gave out more at the lower level as well, but it seems pretty popular so it must be doing well.
That said I do remember when I first hit silver and got 5 cards instead on one I was how cool is that LOL
