'Hearthstone: Mean Streets of Gadgetzan' is coming Dec. 1

Mark your calendars -- the latest Hearthstone expansion, Mean Streets of Gadgetzan, is coming very soon.

Hearthstone: Mean Streets of Gadgetzan is releasing Dec. 1, Blizzard revealed during a live stream showing off a ton of new cards from the expansion and how eight of the nine classes are looking in the new meta.

The stream below begins at 9:44. The Warrior vs. Priest match starts at 11:50, the Priest vs. Hunter match starts at 30:32, the Druid vs. Paladin match starts at 42:05 and the Warlock vs. Rogue match starts at 57:21.

Mean Streets of Gadgetzan introduces a brand-new concept to Hearthstone: tri-class cards. The three crime families in the expansion each represent three classes, and some specific crime family cards can be used by all three classes in that family. The Kabal consists of Mages, Priests and Warlocks; the Grimy Goons are made up of Warriors, Hunters and Paladins; and the Jade Lotus are formed by Druids, Rogues and Shamans.

Check out the tri-class legendary minion Kazakus in action, which allows Kabal classes to create custom potions worth 1, 5 or 10 mana.

A handful of cards have been revealed in the weeks since Mean Streets of Gadgetzan was revealed at BlizzCon in early November, and you can check them out on the Hearthstone Facebook page. If the new cards tickle your fancy, you can pre-purchase 50 packs of Mean Streets cards for $50.
