Worldbreaker brings Goblins and Worgen into the World of Warcraft TCG for the first time, with their own keywords! This new expansion pack also makes new race/class combinations available as Allies and Heroes, and Heirloom equipment will become better the more you have. Green and red dragonflights will take an interest in the Wow TCG, especially their Aspects, Ysera and Alexstrasza. Hero powers will also last much longer than previous ‘one-shot’ powers - and a new keyword makes choosing your resource a lot more interesting!
