With the release of fresh additions, you will be able to crush your rivals with 135 powerful new cards. For a certain time, players can get six sets of cards, a random legendary loa card and two copies of the spirit card (loa and spirit will belong to the same class of hero) for entering the Hearthstone.
Rastakhan’s add-on is available for PCs, tablets, and smartphones. Card sets can be purchased both separately and at a discount in an in-game store — for gold or real money — at the same price as all other Hearthstone card sets.
Rastakhan’s add-on card sets can be rewarded for completing quests and battles in the arena, as well as made from magic dust that comes from spraying unnecessary or least needed cards from the collection.
