The September 2018 Ranked Play Season is now live—and we’re unveiling a new card back you can add to your collection!

The Puzzle Labs are open, so put your gray matter to the test in Dr. Boom’s Lab! After you’ve tussled with the single-player trials that await in the labyrinthine depths of Boom Labs, drag that big brain over to the Ladder and match wits with a worthy opponent! They’ll know you’re on the level when you flash the Dr. Boom’s Lab card back, so queue up for the September Ranked Play Season and make it yours!

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 Dr. Boom’s Lab card back to your collection by winning 5 games at any Rank in either Standard or Wild Ranked Play modes. You’ll receive the Dr. Boom’s Lab card back at the end of September’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 of a head start you’ll get on climbing the ladder the following month. After the Ranked Play season ends, you’ll be reset four Ranks below the highest Rank you achieved the previous season once the new season begins. If you manage to reach Legend, you’ll be reset to Rank 4.

Earn your Ph.D in victory and snag the Dr. Boom’s Lab card back in September’s Ranked Play Season, On the Level!
