Blizzard is moving on to the fourth expansion for its popular digital card game, and now we know when you can expect it.

The Mean Streets of Gadgetzan will debut December 1, which should make it easy for me to figure out what to get GamesBeat editor Jason Wilson and writer Mike Minotti for the holidays. Gadgetzan brings with it 132 new cards to collect, and it also introduces a new tri-class concept that enables players to build decks from a combination of three different standard classes. You can purchase 50 Mean Streets of Gadgetzan decks right now for $50 by going to Gadgetzan.com.

Gadgetzan is a “lawless port city” from Warcraft. In the fiction of that universe, three crime families run all of the operations in Gadgetzan, and they will feature prominently in the expansion. The knee-breaking Grimy Goons, the secretive assassins Jade Lotus, and the mystical Kabal serve as the foundation of the new tri-classes. Hunter, Paladin, and Warrior compose the Grimy Goons. Jade Lotus is Druid, Rogue, and Shaman. While Mage, Priest, and Warlock make up the Kabal.

By enabling players to make decks that can use a larger variety of cards than ever before, Blizzard is seriously shaking up how everyone will have to approach Hearthstone. You can see more of the set here on Blizzard’s Facebook page.
