Diablo IV arrived on the 06/06, breaking several sales records at Blizzard. The company bet on strong and aggressive marketing for the launch of its Action RPG, even going so far as to partner with KFC, a successful franchise in the food business.
The developer took advantage of Hearthstone's large space to continue this aggressive marketing and include some Diablo IV references in the Card Game. The main one, without a doubt, is the Card Back Hail Lilith, which can be unlocked for free and will be a cosmetic kept forever in your account.
To unlock it is very simple: just win a Tavern Brawl in the next 2 weeks. Today's Tavern is The Dark Wanderer, and it's based in the Diablo universe.
Assemble your deck, and face two fights, the first against the Dark Wanderer, and then against Diablo. Don't worry if you lose before winning both matches, your progress will be saved after any defeat.
