Eldrazi Incursion Precon Upgrade Guide: Ulalek Doubling Under $75

2026-06-03 | 4 min read

The Eldrazi Incursion commander deck from Modern Horizons 3 is one of the most powerful and exciting precons ever printed, bringing the legendary Ulalek, Fused Atrocity to the command zone. Ulalek's color identity spans all five colors (thanks to Devoid), but the real soul of the deck lies in its colorless mana requirements and spell-copying triggers.

However, the stock decklist can stumble. It runs several slow 6-mana rocks, low-impact colored removals, and sub-optimal devoid creatures that don't help you execute Ulalek's copying loop.

In this guide, we show you how to upgrade the deck for under $75, focusing on cards that speed up your mana, double down on colorless reflection, and spawn game-ending Eldrazi threats.

The Ulalek Loop: How It Works

Ulalek's text box is a puzzle:

Whenever you cast an Eldrazi spell, you may pay {C}{C}. If you do, copy all other spells you control, then copy all other activated and triggered abilities you control.

To make this trigger consistently, you need:

  1. Colorless Mana ({C}): You must produce {C}{C} easily at instant speed.
  2. Spell Chains: Casting an Eldrazi creature with flash, or using copy engines, lets you copy the original spell and the copy itself, leading to exponential boards.

Curated Upgrades (Under $75 Total)

Our upgrades are organized into three packages: Ramp, Colorless Tech, and Big Finishers.

1. Eldrazi Ramp and Accelerators

Eldrazi are massive, meaning you must ramp early and often. We cut slow, generic mana rocks for explosive colorless accelerators.

  • Conduit of Ruin (~$4.50)
    • Replaces: Dreamstone Hedron
    • Why it's essential: Tutors up any high-end Eldrazi straight to the top of your library and makes the first creature spell you cast each turn cost {2} less.
  • Kozilek's Channeler (~$0.25)
    • Replaces: Sifter of Skulls
    • Why it's essential: A 4/4 body that block early and taps for {C}{C}, leaping you straight from 5 mana to 8 or 9.
  • Thran Dynamo (~$3.00)
    • Replaces: Everflowing Chalice
    • Why it's essential: Turns four mana into three colorless instantly, letting you cast your massive threats multiple turns early.

2. Colorless Tech and Doubling

If copying your spells once is good, copying them three or four times is game-winning. These cards interact directly with colorless and devoid triggers.

  • Echoes of Eternity (~$22.00)
    • Replaces: Crib Swap
    • Why it's essential: A Modern Horizons 3 masterpiece. It copies every colorless spell you cast and every colorless trigger you control. This doubles Ulalek's triggers automatically before you even pay the {C}{C} cost!
  • Roaming Throne (~$28.00)
    • Replaces: Ulamog's Nullifier
    • Why it's essential: Name "Eldrazi" as it enters. Roaming Throne doubles all triggers from your Eldrazi creatures, including Ulalek's command zone copying trigger.

3. Massive Colorless Finishers

When it is time to close the game, you want Eldrazi that force immediate scoops.

  • Kozilek, the Great Distortion (~$9.00)
    • Replaces: Ulamog's Crusher
    • Why it's essential: Fills your hand back up to seven cards on cast and lets you discard cards to counter opposing spells, protecting your massive board.
  • It That Betrays (~$7.00)
    • Replaces: Deepfathom Skulker
    • Why it's essential: A legendary 11/11 Annihilator 2 threat that steals every permanent your opponents are forced to sacrifice.
  • Bane of Bala Ged (~$0.50)
    • Replaces: Twins of Discord
    • Why it's essential: Attacks as a budget-friendly annihilator, forcing defending players to exile two permanents before blockers are even declared.

Easy Cuts from the Precon List

To slot these upgrades in, remove the slowest cards from the stock precon:

  1. Dreamstone Hedron: Too slow at 6 mana to be a ramp card when we want to be casting Eldrazi.
  2. Sifter of Skulls: A slow, reactive token generator. Proactive ramp and cost reducers are far better.
  3. Everflowing Chalice: Weak in a five-color build compared to high-output rocks like Thran Dynamo.
  4. Crib Swap: Exiling a creature is nice, but leaving a 1/1 token behind is weak when we could run massive colorless synergy engines.
  5. Ulamog's Nullifier: A counterspell that requires cards in your opponents' exile zones is too conditional in typical Commander pods.
  6. Ulamog's Crusher: A solid budget card, but Kozilek provides game-winning card draw and counter protection for a similar mana cost.
  7. Deepfathom Skulker: Draws cards when creatures deal combat damage, but we have better draw spells and Kozilek to draw on cast.
  8. Twins of Discord: Provides a temporary combat block, but Bane of Bala Ged forces immediate exiling of permanents and closes games faster.
