Magic: The Gathering’s upcoming set Reality Fractureis the culmination of a three-year plot arc and the 19-year story of Jace Beleren, the mind mage who has become one of the game’s most iconic characters. Now calling himself The Theorist, Jace has decided to reshape reality in his image, creating a parallel multiverse called the Echoverse. Reality Fracture’s designers have come up with numerous ways to make sure Jace’s influence feels ever-present, and Polygon can exclusively reveal three cards that showcase his conflict with the other Planeswalkers of Lorwyn as they try to save the world.
