Hearthstone, a card-based fighting game that's not unlike an electronic version of Magic: The Gathering, has proven to be popular on the eSports scene, especially the banter-laden team games. It appeals to both casual gamers and pros because it's relatively easy to learn and find opponents. At the same time, it requires sophisticated strategies at the highest levels.

The format will pit powerhouse nations like the US against much smaller ones, including Peru and Belgium. Blizzard says that teams will seeded by their respective countries (based on winter season points) with the first team member being the top-ranked player, and the other three chosen from a pool of eight by the Hearthstone community. The tournament will run a best-of-five format, class versus class format, with each team player representing two classes of cards.

Top players including Edwin "HotMEOWTH" Cook and Russian world champ Pavel Beltukov, will compete for $300,000 in the competition. So far, no dates have been announced, but you can check out the video below for action in last year's championships.
