Deck overview

This deck is a specialized 4-color ({W}{U}{B}{R}) Polymorph Control strategy led by Jace, Multiverse Architect. By completely omitting low-mana creature cards from the 99, the deck guarantees that every Polymorph trigger—whether from Jace's -3 loyalty ability, Proteus Staff, Mass Polymorph, or Synthetic Destiny—flips directly into a devastating 6-to-10 CMC creature bomb. The early game focuses on deploying 2-CMC mana rocks and noncreature token generators like Skrelv's Hive, Dreadhorde Invasion, and Black Market Connections. On Turn 4, Jace enters the battlefield and immediately sacrifices a token to cheat in format-defining threats such as Archon of Cruelty, Hullbreaker Horror, Serra's Emissary, or Ovika, Enigma Goliath. Jace's static combat tax protects his loyalty from opposing attacks, while top-deck manipulators like Brainstorm and Brainsurge tuck drawn bombs back into the library. The deck smoothly transitions from explosive early cheating into overwhelming mid-game attrition, closing games out around Turn 7.
