Deck overview

This deck is a 4-color Polymorph strategy helmed by Jace, Multiverse Architect. The game plan revolves around generating cheap creature tokens through cards like Dreadhorde Invasion, Skrelv's Hive, and Kher Keep, then deploying Jace on Turn 4 to activate his -3 ability. This exiles a token to reveal and cheat massive, game-dominating creatures such as Archon of Cruelty, It That Betrays, Serra's Emissary, and Archfiend of Despair directly onto the battlefield. The deck supports this core engine with dense 2-CMC mana acceleration, reliable interaction, and robust protection cards like Flawless Maneuver and Ripples of Potential. Backup polymorph effects like Proteus Staff ensure resilience if the commander is removed. Victory is achieved by overwhelming the table across multiple combat cycles while Jace's passive tax and defensive haymakers suppress opposing counterattacks.
