Each starter pack contains:
A starter pack has everything you need to get you started. You will get a playable deck, and two boosters. Since the deck will be below the minimum requirement for sanctioned play (torunaments) you won't be able to use it in official events until you've got 60 or more cards but that won't be too tough. You will get plenty of cards from the 2 booster packs, that which you can't use can be traded.
