Wizards of the Coast announces Duels of the Planeswalkers 2012, a new videogame based on the Magic: The Gathering card-based strategy games set for release this summer for PC (Steam), Xbox LIVE Arcade, and PlayStation Network. Word is: "With an easy to use tutorial, Duels of the Planeswalkers is the best way for new players to learn Magic: The Gathering. Players that are already familiar with Magic will enjoy a new-to-digital multiplayer game mode called Archenemy where players gather up to two allies and team up against the AI." The game will be playable at PAX East, which gets underway today. Here are some screenshots, and here's a gameplay-free teaser trailer, which is embedded below.
