Deck overview

This four-color deck uses Jace, Multiverse Architect as a dedicated Polymorph engine in the command zone. The list runs zero small utility creatures or mana dorks, ensuring that every polymorph activation hits a devastating boss monster from a curated pool of thirteen game-ending threats. During the early turns, the deck fixes its mana with two-mana artifact rocks and establishes low-cost token generators such as Skrelv's Hive, Dreadhorde Invasion, and Lingering Souls. On Turn 4, Jace enters the battlefield and immediately uses his minus-three ability to exile a token and put a massive threat like Archon of Cruelty, Ulamog's Dreadsire, or Serra's Emissary into play. Supported by flexible white and black removal, efficient board sweepers, and backup polymorph spells in the ninety-nine, the deck quickly overwhelms the table with massive flying and Eldrazi attackers.
