The highlight of the update is that the 19.4 patch includes Hearthstone’s first-ever Mini-Set expansion, The Darkmoon Races. The Mini-Set features a total of 35 unique cards, including 4 Legendary, 1 Epic (x2), 14 Rare (x2), and 16 Common (x2); this comes to a total of 66 cards. The cards in the Mini-Set are in line with the same mechanics that come alongside theYear of the Pheonix! inHearthstone,which was the final major expansion of 2020. The Darkmoon Races Mini-Set cards can be found in the Madness at the Darkmoon Faire card packs.

The Battlegrounds updates are also important. New Heroes Greybough and Tickatus are being added, and new Minions are joining as well, including Soul Devourer and Ring Matron. Meanwhile, a Mid-Season Update to Duels will add 10 new Hero Powers, 25 new Signature Treasures, and more.
