This week's brawl is Brawl Block: Gods, Gadgetzan, Gurubashi!
"Construct a deck using ONLY cards from Whispers of the Old Gods, Mean Streets of Gadgetzan and Rastakhan's Rumble!"
The rules are clear, you'll be creating your own deck this week from a limited card pool of these three expansions!
If you don't really feel like building a deck right now, and don't want to wait for people to submit theirs to HearthPwn: The auto complete deck feature is a good option! It'll make a decent deck from the best cards you own.
