If you like your Hearthstone [Free] classes mixed up or want to get a taste of how two-class decks would look, go play Cart Crash at the Crossroads, this week's Tavern Brawl. We've played this one in the past, but as is the case after every expansion, new cards make for fresh brawls. Cart Crash at the Crossroads has you picking a class and getting a random deck, and on the first turn, you get to Discover another class. While your hero power remains the one of your original class, your deck becomes a mix of random cards from both classes. Keep in mind that your win only count towards quests for the original hero you picked.

As you can guess, some class combinations are more OP than other ones, so experiment a bit to see what works best. I'm hoping to see Brawls where we get to construct decks from two or more classes in the near future because that will make for fun matches.
