This five-color Eldrazi deck revolves around **Ulalek, Fused Atrocity**, leveraging token generation, cost reduction, and spell/ability copying to deploy massive Eldrazi threats. The commander amplifies board impact by copying all spells/abilities whenever an Eldrazi is cast (with {C}{C} payment), enabling explosive turns with token armies, annihilator triggers, and value engines. Secondary synergies include **Morophon, the Boundless** as a hidden commander for cost reduction and tribal buffs, alongside recursive tools like **Spawnbed Protector** and **Artisan of Kozilek**. The deck aims to win through overwhelming combat damage, annihilator pressure, and token swarms enhanced by **Eldrazi Monument** or **Forsaken Monument**.
