Hearthstone's Next Adventure, One Night In Karazhan, Begins August 11th

Blizzard announced late last night that Hearthstone's next adventure will be called One Night In Karazhan. The story of this adventure is that you're invited to a party at "Azeroth’s most terrific tower—Karazhan" as a guest of the wizard Medivh. The adventure will introduce new cards, a new board, new class challenges, and more, most of the details of which have yet to be revealed. What we do know is that there will be portal spell cards and that they may make things a bit hectic.

It has also been announced that the adventure will have a prologue chapter. Just by playing the prologue, players will be given two copies of both the Enchanted Raven and Firelands Portal cards.
