It's called "brilliant business strategy."

Over the last few weeks, Cody "Micajah" Bye had the opportunity to play-test the World of Warcraft Trading Card Game, doing so with an initial purchase of $50. However, while he was opening his starter deck and booster packs, Cody made a truly harsh discovery; there were so many different cards he might not be able to make a second deck, even with 150 additional cards to play with! Was this a fault of the card game, or is it just the nature of the TCG beast?

I'd received a huge variety of cards from various classes and alignments, but with such a diversity to choose from I ended up with a dabbling of Priest cards and a single wizard card, five extra rogue cards and ten druid cards. There was a huge spread and if it weren't for my warrior cards (which totaled around 20) I wouldn't have had enough cards in a single class/alignment to actually play more than one style of deck.
