Today Hearthstone is receiving a major update that will add a new Tavern Brawl mode. The patch also brings three new Heroes for players to purchase.
Tavern Brawl mode has a new set of rules every week. For example, the first week of Brawl is called "Showdown at Blackrock Mountain" and challenges players to become Ragnaros or Nefarian. During this match between the two Blackrock Mountain villains, players will use a premade deck with cards not attainable anywhere else.
Future Tavern Brawls will have very different mechanics. One week you might be asked to create your own deck to fit specific requirements. Another week, certain minions could get a big buff.
Tavern Brawl will follow the same schedule each week. Here's the time table for each region:
The new heroes, however, won't be free. You'll have to pay $10 to unlock Magni, Medivh or Alleria for your collection. These heroes can be swapped in for the default characters in the Warrior, Mage and Hunter classes respectively. The new Heroes come with different animations and voiceover. Buying one of the Heroes also unlocks a matching card back. Their Hero ability and card selection are the same as the other characters in their class, though.
