According to Blizzard, they will be giving away two cards to players who just play through the free prologue mission. “The magus Medivh is hosting the party of the millennium in the magical, magnificent tower of Karazhan. A shindig sure to go down in legend has just begun, but before you dance the night away with Azeroth’s most glamorous people, you’ll first meet up with Medivh in the free Prologue mission. Better yet, you’ll pick up two copies each of Enchanted Raven and Firelands Portal just for stopping by.”
If you like what you see, players will be able to purchase all four wings for $20. Alternatively, gamers can purchase the wings individually at $7 or 700 gold each. This will also be taken into consideration if you purchase individual wings but decide to buy a package later. However to tempt gamers to purchase all the wings at once, Blizzard will be giving gamers a Karazhan Nights cardback if they were to make the purchase in the first week.
If you’re interested in getting your hands on the game, fire up Hearthstone to purchase it. Alternatively you can also check out the entire collection of cards that are released in this adventure on the Hearthstone Facebook page.
