Deck overview

This deck is a four-color Polymorph strategy helmed by Jace, Multiverse Architect. The primary game plan deploys low-cost token generators, noncreature artifacts, and manlands during the early turns to establish expendable fodder. On Turn 5, casting Jace and using his −3 loyalty ability allows the pilot to exile a token and flip directly into one of 16 high-impact creatures or planeswalkers, such as Serra's Emissary, The Ur-Sphinx, Magister Sphinx, or Velomachus Lorehold. Top-deck manipulation cards like Brainstorm and See Beyond tuck drawn bombs back into the library, ensuring polymorph effects remain loaded. Once on the battlefield, these massive evasive threats generate compounding card advantage, lock out opposing combat steps, and eliminate the table across three subsequent combat rotations. Efficient white and blue spot removal guards the pilot's life total throughout setup.
