Mastermind mage Jace Beleren has pushed reality to its breaking point. An alternate Multiverse of his own creation threatens to overtake the current one, and just one brave team of heroes stands in the path of oblivion. Be on the lookout for twisted new reflections of Magic' legends as you explore Jace's Echoverse and his inner sanctum within the dystopian school of Hexhaven.

Smash through the looking glass and discover a whole new Multiverse of wonders! Every Reality Fracture Collector Booster contains Rares and/or Mythics, Traditional Foils, and a Borderless basic land to begin sculpting your perfect sanctum. You may even happen upon 1 of only 500 Headliner Serialized cards* (found in <1% of Collector Boosters).
