A new Tavern Brawl is now live on Hearthstone servers around the world, and this week sees the return of Miniature Warfare. This is the third time the Brawl has appeared in the game since its debut back in January 2016.
Here's the official description, straight from the game:
That pesky Shrinkmeister turned all your Hearthstone cards into toys. Now all your minions are 1 / 1 and only cost 1 Mana!
You'll need to craft an original deck of your own this week, but note that every minion you include will have stats of 1 / 1 and will only cost 1 Mana to play.
This is a good opportunity to fill your deck with lots of Legendary cards that dish out more power through Battlecry effects than their stats - pro-tip: pack an Alexstrasza if you have one.
The Tavern Brawl will be active until 3am PDT this Monday, and if you manage to win at least one match before then you'll unlock a free Classic card pack for your account. Any wins you achieve after your first however, are strictly for bragging rights.
