Hearthstone's fourth official season kicked off yesterday, and with it came the promise of another new card back for those able to reach rank 20. The Dread Necropolis is an obvious nod to the coming Curse of Naxxramas adventure pack, which could be out as early as this month. While the task might seem like a tall order if you're new, just remember, you're not penalized for losing prior to rank 20, making the journey far less painful than it could be.
Brave adventurers might recall Naxxramas as the lich Kel'thuzad's floating abode in Wrath of the Lich King. The card back boasts an appropriate motif, complete with bones and the raid's signature purple and green color scheme.
