Hearthstone Community Event Spreads Free Viral Card Back

Blizzard is kicking off a new Hearthstone community event today that will spread a nifty reward around like a virus. The "Curse of Hakkar" event features a new exclusive card back that has been distributed to a small group of players, but will infect everyone who comes in contact with it.

Playing against a player with the new "Mark of Hakkar" card back will reward you with it. Then you can equip it and begin spreading it to others. You'll need to play a full match to spread the item, so conceding or leaving immediately won't get you the reward. If you want to gift it to your friends, you can queue up friendly matches to distribute it to them.

The community event is a reference to one of the cards from the most recent expansion, Rastakhan's Rumble. Hakkar the Soulflayer is a neutral Legendary card that shuffles "Corrupted Blood" into each player's deck upon dying. That Corrupted Blood replicates and multiplies itself, so if a match goes on long enough it makes going to fatigue much more risky. It also serves as a hard counter to Mecha'thun, which requires an empty deck to function.

Recently Blizzard announced a new set of balance changes coming to Hearthstone, which strike particularly hard at classic mainstays that have been used in multiple decks across the game's lifespan. This all comes in advance of the new Standard rotation, which will cycle when the first expansion of 2019 releases. That will rotate out all the cards from Journey to Un'Goro, Knights of the Frozen Throne, and Kobolds and Catacombs, to make room for this year's new sets.
