Hearthstone’s July 2015 Ranked Play Season: Darkspear Delight! is coming to a close at the end of the month, and your chances of acquiring the Darkspear card back for your collection will soon come to an end!

This tribal card back will only be available during July, so be sure to hit Rank 20 before the 1st of August and the card back will be awarded to you at the end of the season.

The August 2015 season—and a new card back along with it—await you next month!
