The third official Hearthstone Ranked Play Season is now live! Best of all, we’re unveiling a new card back you can add to your collection!

Partake in some merry battles up the Ranked Play ladder to earn the joyful Rainbow! card back. You will only be able to earn this card during the month of June.

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 Rainbow! card back to your collection by hitting Rank 20 in Ranked Play mode. The Rainbow! card back will be awarded to you at the end of June’s Ranked Play Season.

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!

If you’re looking for a challenge, aim for the real pot of gold at the end of the rainbow – the $250,000 prize pool at the Hearthstone World Championship at BlizzCon 2014!

Craft a deck, take a seat in the tavern, and admire all the Colors of the Rainbow! with our third official  Ranked Play Season, running through the month of June!
