Hearthstone's Craziest New Legendary Is 18 Decks In 1

Hearthstone's upcoming Boomsday expansion pack looks to be filled with wild cards, including three synergistic Druid cards which we recently revealed. But while the return of Dr. Boom and a Rogue spell that literally draws your entire deck are hard to ignore, the most interesting card in the expansion so far is probably a newly revealed neutral Legendary: Whizbang the Wonderful.
Whizbang the Wonderful is a 4-mana 4/5, but you won't play him for his stats. In fact, you won't play him at all, because his effect totally rewrites your deck. As designer Peter Whalen explained in a new Hearthside Chat, when you add Whizbang to your deck, every other card and even your choice of pahlawan is thrown out, and your deck is renamed to "Whizbang is Wonderful." And when you queue into a match with a Whizbang deck, your deck turns into one of 18 possible decks—more specifically, one of the most recent 18 deck recipes across all nine classes. In other words, you won't know what class and archetype you're playing until you queue into a match.
