If you want some randomness in your week, go play this week’s Hearthstone (Free) Tavern Brawl, Valeera’s Bag of Burgled Spells. You’ve probably played this brawl before, but if you haven’t, be prepared for a spell-tastic week. You’ll get a deck full of random spells from all classes, and every time you cast a spell, a minion of the same cost is summoned. Think of this as randomness squared. At the same time, knowing the cost of the minions does give you a semblance of control over what kind of minions will end up on your board. Keep in mind that spells are cast after the minion is summoned, so if you play a spell like Twisting Nether, it will summon a minion and then clear the board.
Unfortunately, you’ll get a Classic pack once you beat this Brawl, so if you were hoping for some more Un’Goro goodies, I’m sorry to disappoint. The brawl is live in the Americas, so go enjoy the randomness.
