The October Ranked Play Season is now live—and we’re unveiling a new card back you can add to your collection!

True masters of disease, decay, and undeath, Unholy Death Knights embody the pestilential horror of the Scourge, spreading plague and bringing death wherever they tread! The art on this month’s card back is sick, so make sure your collection contracts the gangrenous green Unholy Knight card back by playing Hearthstone during the month of October.

These card backs replace the art decorating the reverse side of your cards and are a great way to show off your Hearthstone accomplishments. Add the Unholy Knight card back to your collection by hitting Rank 20 in either Standard or Wild Ranked Play modes. You’ll receive the Unholy Knight card back at the end of October’s Ranked Play Season in your Ranked Play reward chest.

You earn Ranked Play reward chests based on your highest earned rank over the course of a Ranked Play season. Reward chests may contain seasonal card backs, Arcane Dust, and golden cards, and can be obtained by playing in either Standard or Wild Ranked Play modes. You’ll be awarded one chest per Ranked Play season based on your highest rank between the two modes.

Don’t forget—the further you move up the Ranked Play ladder, the more bonus stars you’ll receive next season. In Ranked Play, you’ll receive bonus stars based on your performance from the previous season—one bonus star per rank you attained. Please note that even if bonus stars from the previous season get you directly to Rank 20 or above, you still have to log in at least once each Ranked Season to qualify for the card back reward.

Show your opponents the true meaning of terror in October’s Ranked Play Season: Unholy Horror Knights!
