Hearthstone - Heroes of Warcraft news » Hearthstone® February 2017 Ranked Play Season—Come one, Kabal!

The Kabal welcomes all who embrace the power of the potion! Master alchemist Kazakus has taken note of your reckless disregard for safety in your pursuit of power and feels that your passion should be rewarded. Use this to display your prowess with potions—the Kabal card back!

These card backs replace the art decorating the reverse side of your cards and are a great way to declare your devotion to the Kabal. Add this badge of honor to your collection by hitting Rank 20 in either Standard or Wild Ranked Play modes. You’ll receive the Kabal card back at the end of February’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.

A new red mana shipment just arrived in the port. With these crystals and your expertise among our ranks, the Kabal will be unstoppable on the Mean Streets of Gadgetzan!
