Hearthstone: Heroes of Warcraft, is Blizzard’s brand new video game. The official announcement was made in the Pax East gaming convention on Friday and the beta testing is about to begin.

Despite its name, the game is a stand-alone and free-to-play trading card game, along the lines of the classic Magic the Gathering. Players don’t have to own a WOW account, but they’ll have to log in Battle.net to be able to download and play the game.

Players will be able to gain cards by winning matches or trading them, and the impatient ones can always pay to speed things up. Cards will come in packs of 5 (randomly generated), each costing $1. By destroying unneeded or duplicate cards the players would be able to create a mana pool and use it to get better and rarer cards later on.

For the record, the greatest competitors, in this space-time, are the newly launched Magic the Gathering: Duel of the Planeswalkers from the Wizards of the Coast, and the fresh Scrolls from Mojang.

At the moment, Hearthstone is accepting sign-ups for its beta test in North America. The rest of the world will have to wait. According to the company, the game will be ready to launch by the end of 2013 and will be initially available for Windows and Mac, and a version for iPad will follow shortly.
