Rakdos Preview Pack (black/red), inside, you will find five normal Ravnica's Allegiance boosters, and one special "classified" booster. This booster contains one of the eight rare or mythical rare cards that will be your Preview card, as well as a stack of cards to give you a head start in building a deck in both suits of that guild. There are some themes in the boosters built around the rare/mythical rare card you get (not to mention the mana stabilization cards!) so this should help you get the most out of your deck.
