The Polycule by LivingCheese

Format: Commander

Commander: Jace, Multiverse Architect

Bracket: 3

DeckCheck Threat Index: 39

Deck overview

This deck leverages Jace, Multiverse Architect as a guaranteed command-zone Polymorph engine. The primary game plan focuses on deploying cheap token generators such as Skrelv's Hive and Dreadhorde Invasion alongside efficient mana rocks during the opening three turns. On Turn 4, Jace enters the battlefield and uses his −3 loyalty ability to transform an expendable token into one of ten devastating game-ending creatures, including Hullbreaker Horror, Tidespout Tyrant, and Ovika, Enigma Goliath. Once a threat resolves, the deck converts noncreature spells into continuous board denial, bouncing opposing lands and threats while expanding its own board. Supporting cheat spells such as Polymorph, Synthetic Destiny, and Reality Scramble ensure high redundancy even if Jace is removed. With built-in attack taxes on the commander and asymmetric attrition from massive threats, the deck swiftly controls the table and closes the game through overwhelming combat damage.
