The October Ranked Play Season is live and a new card back is ready to be added to your collection! Its art is sick, depicting death, horror and the spreading plague of the Unholy Death Knights.
The new card backs replace the art decorating the reverse side of your cards and are a great way to show off your Hearthstone accomplishments. You can add the Unholy Knight card back to your collection by hitting Rank 20 in either Standard or Wild Ranked Play modes. Note that you will receive the card back at the end of October’s Ranked Play Season in your Ranked Play reward chest. Reward Chests will be awarded once per Ranked Play season based on your highest rank between the two modes and may include seasonal card backs, Arcane Dust and golden cards.
