Today, the Duels of the Planeswalkers 2013 expansion was released on Steam, Xbox LIVE Arcade, the iPad, and the PlayStation Network. The expansion adds content that will set the tone for the upcoming Return to Ravnica block. With five new decks, each themed after one of the guilds in the Return to Ravnica set, players will be able to experience firsthand the Azorius, Izzet, Selesnya, Golgari, and Rakdos playstyles.
In addition to the five new two-color decks, five levels have been added to both the Regular and Revenge campaigns, as well as five puzzle challenges. A number of new portraits, trophies, and more have also been added to the game.
