The second boss in The Opera is the Big Bad Wolf. It’s a fun battle, you get all your cards reduced to 1 mana and 1/1 stats, but this just makes it even easier to win by playing lots of cards.
I don’t even need to outline a strategy here, I did it with some basic mage cards no problem. Have fun!
The card reads: Deathrattle: Summon a 3/2 Big Bad Wolf.
This card is going to see a lot of play. It’s a really strong 2 drop with beast synergy, Barnes synergy, and is just an awesome choice on turn two for hunters.
