The 19.4 patch, launching on January 21, brings the first-ever Mid-Season Update for Duels! All players’ Duels ratings will be reset for Casual and Heroic, the Darkmoon Races Mini-Set will be added to the pool of eligible cards you can use to build your 15-card starter deck, and each class will gain access to one new Hero Power and three new Signature Treasures—one of which is Dual-Class! Lastly, we’re adding 4 new Passive Treasures and 2 new Active Treasures for you to supplement your deck with between games.

Each class will now have access to 3 Hero Powers and 6 Signature Treasures in total! These new Hero Powers and Treasures can be unlocked by meeting the below criteria associated with your Collection.
