Duplicating spell casts alongside every activated and triggered ability on the stack turns high-cost cosmic horrors into immediate board-wiping overruns. On Moxfield’s high-power and casual deck charts, few five-color commanders create as much jaw-dropping stack manipulation as Ulalek, Fused Atrocity.
As a 2/5 Deathtouch legend costing five generic mana (), Ulalek possesses a color identity of all five colors (). Whenever you cast an Eldrazi spell, you may pay two colorless mana. If you do, you copy all other spells you control on the stack, then copy all other activated and triggered abilities you control on the stack. By combining Ulalek with stack duplicators like Echoes of Eternity and colorless mana engines like Forsaken Monument, you can trigger exponential copy loops that flood the battlefield with duplicated Eldrazi Titans.
Here is the strategic operational blueprint of Moxfield’s premier Ulalek list, detailing how to turn colorless mana acceleration into total stack duplication and eldritch victory.
1. Core Mechanics & Strategic Phases
Succeeding with Ulalek requires a deck structure dense with colorless mana acceleration, Eldrazi kindred synergies, stack-doubling engines, and land fixing across all five colors.
-
Early Game (Turns 1–2): Ramp aggressively using colorless mana rocks like Sol Ring, Mana Crypt, and Eldrazi ramp pieces like Eldrazi Temple or Eye of Ugin.
-
Mid Game (Turns 3–4): Deploy Ulalek, Fused Atrocity and build your colorless mana production using Forsaken Monument or Hedron Archive to ensure you always have cc open.
-
Late Game (Turns 5+): Cast massive Eldrazi spells such as Ulamog, the Defiler or Kozilek, the Broken Reality, pay Ulalek’s cc trigger to duplicate the spells and cast abilities on the stack, and overwhelm opponents with duplicated titans.
2. Moxfield Highlights: Fusion of the Titans
The highest-rated community lists on Moxfield optimize Ulalek by pairing his stack-duplication ability with raw colorless mana production, cost reducers, and game-ending Eldrazi triggers.
Echoes of Eternity
The premier Eldrazi stack multiplier. Echoes of Eternity causes every colorless spell and trigger to trigger an additional time. When paired with Ulalek, a single Eldrazi cast creates multiple cascading copy triggers that duplicate your entire stack exponentially.
Forsaken Monument / Eldrazi Temple
Essential colorless mana anchors. Forsaken Monument makes all your colorless sources produce an additional c, gives colorless creatures +2/+2, and gains you life whenever you cast a colorless spell, easily satisfying Ulalek’s cc copy cost.
Kozilek, the Broken Reality / Ulamog, the Defiler
Massive Eldrazi cast-trigger payoffs. Because Ulalek copies spells and abilities on the stack, casting Kozilek or Ulamog while holding cc lets you duplicate their destructive cast triggers (card draw, board exiling, and opponent deck annihilation) before the physical creature cards even enter play.
Chittering Dispatcher / Snapping Voidcraw
Cheap Eldrazi spell enablers. Low-cost Eldrazi allow you to trigger Ulalek early or weave low-cost spells into stack loops to copy heavier triggers already waiting on the stack.
