I only just joined in July, but I love the 2x2 format. You get two sets of two Penguin
Magic-exclusive decks. I use my cards, so this gives me the option of keeping one sealed for my
collection. If I really love the cards (see: Architects), I'll use both decks and buy more. August
seems to be following the trend of offering decks I find desirable, so it's a win so far.
