Deck overview

This deck is a four-color Polymorph Midrange strategy piloted by Jace, Multiverse Architect. The primary plan relies on deploying low-cost token generators in the opening turns—such as Skrelv's Hive, Lingering Souls, and Grand Crescendo—before casting Jace on Turn 4. By activating his −3 loyalty ability targeting a disposable token, Jace reliably reveals through the library to cheat a massive creature or planeswalker onto the battlefield, including Archon of Cruelty, Serra's Emissary, Avacyn, Angel of Horror, or Darksteel Angel. A dense suite of 2-CMC mana rocks ensures consistent Turn 4 execution, while Jace's passive combat tax deters crackbacks from opposing attackers. Redundant cheat spells like Mass Polymorph, Synthetic Destiny, and Proteus Staff provide resilience if Jace is answered. The deck steadily dismantles opposing boards through evasive combat and compounding attrition, closing games across three response cycles backed by flexible removal and board protection.
