More improvements are coming to Hearthstone!

Blizzard has announced what Constructed Arena where you build one Standard deck and try to get to 12 wins before you reach three losses and are eliminated! Details below.

Update 10/18/16: We have confirmed with Blizzard that the brawl will not be this week. So you still have time to start saving up gold!

Over on Reddit, Lead Designer Ben Brode confirms that going 0-3 in your run will only net you a single pack! On the other hand, he says this means they can ratchet up the rewards on the higher end of the spectrum.

This brawl is pretty different. We want it to feel more like a tournament, and so the rewards are weighted heavily towards the high end of wins. The reward for 0 wins is a single pack. If this scares you, you may want to wait for next week's Brawl and just enjoy the fun on Twitch. :)Updat

 

Update 10/27/16: Though Brode originally tweeted that the brawl was scheduled to come out before BlizzCon, that's no longer the case.

I'm not sure that's the case after all. #soon

 

Zeriyah also did some talking about the new Tavern Brawl and how it will replace those free Tavern Brawls you've now gotten used to. She also confirms that there is no scheduled return for Heroic Brawl yet, it depends on how things go.

For the rewards, it is like Arena - you'll still get a little something if you don't go all the way to 12 wins.

Once this Brawl goes live (it takes over the spot of a "normal" Tavern Brawl), it'll last for however long a normal Tavern Brawl lasts in your region.
No, Heroic Tavern Brawl will take over the normal Tavern Brawl. Free Brawls will return once Heroic Brawl is over!
The pack rewards are from the most recent expansion - so it would be Whispers of the Old Gods. The Legendaries are random.
The current limit is five runs.

 

Here are how the rewards will stack up:

Ready for the ultimate competitive Tavern Brawl experience that will test Hearthstone’s best in an all-out battle for glory? If you think you’re up to the challenge, get your deck ready and dive into the fray, because Heroic Brawl is coming!

Heroic Brawl will challenge even Hearthstone’s most experienced players as they vie for glory and in-game rewards! Participants will create a Standard deck from their existing card pool and lock it in before their first Heroic Brawl match. No changes can be made to your Heroic Brawl deck once you’ve locked it in, so be sure to do a bit of testing before you finalize your deck.

Once you’ve locked in your Standard deck for Heroic Brawl, you’ll be pitted against other Heroic Brawlers in heated battle. Just like the Arena, you want to shoot for 12 wins to get the best rewards—but if you get three losses, you’re out!

For Hearthstone’s best brawlers, 50 packs, a heap of Gold, piles of Arcane Dust, and three golden Legendaries sit at the end of the 12-win rainbow. The rewards are significantly different than what you have come to expect in the Arena, and the more games you win, the better they get. Are you ready to take on the best and brightest of competitive Hearthstone?

Heroic Brawl is not for the faint of heart, and is a unique experience meant for the extremely competitive and experienced Hearthstone player. To speak more on Heroic Brawl and the philosophy behind it are two of Hearthstone’s game designers for Tavern Brawls, Dan Emmons and Pat Nagle.

Are you cracking your knuckles in anticipation yet? Here’s how you can participate!

Heroic Brawl lasts for only one normal Tavern Brawl week and has an entry fee of $9.99 USD or 1000 gold. You can participate in Heroic Brawl for a limited amount of completed runs. As mentioned above, Heroic Brawl rewards scale depending on how many wins you get, so be sure to do your best each run!

If you’re not ready to throw down during Heroic Brawl week, you can watch your friends Brawl with Spectator Mode or cheer on your favorite streamers as they go for the gold. We’ll return to our normal Tavern Brawl schedule after the conclusion of the Heroic Tavern Brawl week.

We hope that our Heroic Brawl scratches the competitive itch of the players looking for a high risk, high reward experience. Heroic Brawl is coming soon, so keep an eye out for updates.

We’re always looking to try new things in Hearthstone, so let us know what you think of Heroic Brawl on the official Hearthstone forums!
