Hearthstone: Whispers of the Old Gods’ 5 most promising new cards

GamesBeat is here to help you prepare for the next age of Hearthstone.

The Whispers of the Old Gods expansion adds 134 cards to the free-to-play game when it launches on April 26. Hearthstone is the leader in the $1.2 billion digital card games market and makes over $20 million a month. This expansion will help keep users engaged (and buying more cards). It will also bring in new players who are behind on their collections — or avoided the game because they feared they could never catch up on cards.
