Earlier this year, Blizzard announced it was tossing it's hat into the rapidly swelling ring of free to play titles with the reveal of Hearthstone: Heroes of Warcraft, which is in beta now. The card battler game pitted heroes from the Warcraft universe against each other PvP style to earn gold and unlock new cards. Players will utilize some of the series' iconic characters, items, and abilities in a system that appears somewhat similar to Magic the Gathering.
