Each week will see a new Tavern Brawl, with players able to participate in special matches with unique rules, such as requiring players to use special premade decks, providing bonuses to specific minion types, or even taking on the roles of infamous Hearthstone villains.
Tavern Brawls will be time-limited, with each unique Brawl only available for about a week. During that time, players can play as many Tavern Brawls as they like. Players will also be able to directly challenge friends to Tavern Brawls.
For full details, screenshots, and deck lists, see Tavern Brawl.
