War of the Elements is the second release in the Worldbreaker block.
War of the Elements picks up the Catclysm storyline where Worldbreaker left off. This time the focus is on the Elemental War that has been brought about by the return of Deathwing. Players can align themselves with one of the Elemental Lords that are playable allies for the first time. There will be 1 for each of the primary elements - Fire, Earth, Air, & Water. Blue & Bronze Dragonflights and their minions are a theme in this set. The Blue Dragonflight gets a Master Hero card for Kalecgos and the Bronze for Nozdormu. The set features the Stash mechanic, where players can gain an effect for using a non-quest card as a resource. Goblins and Worgen are plentiful, along with their respective abilities: Time Is Money and Aberration. The common loot card is a version of a companion pet, Lil' KT (a mini version of Kel'Thuzad). The rare loot card will be a ground mount (TBA).
