On Xbox Live, PSN, Steam and the App Store.
Wizards of the Coast have released have released the Duels of the Planeswalkers 2013 expansion pack for their game, Magic: The Gathering. You can download it via XBox Live Arcade for the Xbox 360, PlayStation Network for the PS3, Steam for PC and the App Store for your iPad devices.
The expansion pack features five of the guilds of Ravnica, along with the following new features:
One in a million sentient beings are born with “the spark,” the ineffable essence that makes an individual capable of becoming a Planeswalker. Of those born with “the spark,” even fewer “ignite” their spark, enabling them to realize their potential and travel the planes. Most Planeswalkers have their spark ignited as the result of a great crisis or trauma, but every awakening is different. A near-death experience might ignite a Planeswalker’s spark, but so could a sudden, life-changing epiphany or a meditative trance that enables the mage’s grasp of some transcendent truth. There are as many such stories as there are Planeswalkers.
