does not simply “double an Eldrazi.” It reads your side of the stack at the moment a paid trigger resolves. The spell, its cast abilities, and any engine triggers still waiting there are separate objects—and each can multiply differently.
ENGINE / 01
The copier
Each Eldrazi cast creates one optional {C}{C} checkpoint. A paid trigger copies every spell you control, then every other non-mana activated and triggered ability you control that is still waiting on the stack.
ENGINE / 02
The loop handle
Pay {1} and tap it while 's trigger is on the stack. The copied trigger resolves first and can copy the original trigger, preserving another checkpoint for the next {C}{C} payment.
ENGINE / 03
The trigger doubler
is another colorless permanent, so makes its ability trigger an additional time even for a colored Eldrazi spell. supplies its own spell-copy trigger only when that spell is colorless.
ENGINE / 04
The tribal relay
Choose Eldrazi. Its spell-copy trigger can wait below , allowing every paid trigger to copy that ability before it resolves. It also recognizes Kindred spells and changeling.

NO · PAY NOTHING
The current trigger does nothing. Let copied spells and abilities resolve; eventually decline or pay any original trigger still waiting.
The copied Eldrazi spells are put directly on the stack; they are not cast, so they do not create fresh cast triggers. The growth comes from copying the trigger that was already waiting.

PLAYBOOK / SEVEN CASES
What the deck can actually multiply
The same engine produces very different value depending on whether the payload is a spell, a cast trigger, a nonlegendary body, or all three.
CASE / 01 · Clean exponential line
Snapping Voidcraw
Nonlegendary, colorless through devoid, and free of cast triggers. It makes the sequence easy to count: each paid copied trigger doubles the pending spells.
CASE / 02 · Bodies watch the copies behind them
Glaring Fleshraker
Resolving permanent-spell copies enter one at a time. With N Fleshrakers, the earlier bodies generate N × (N − 1) ÷ 2 damage triggers as the later ones enter; makes each of those triggers happen twice.
CASE / 03 · Kicker survives copying
Sowing Mycospawn
A spell copy remembers that the original was kicked. The copied spell is not cast again, but separately copies the land-search and kicked land-exile triggers already on the stack.
CASE / 04 · X and modes stay locked
Kozilek's Command
Every copy keeps the original value of X and the same two chosen modes. You may redirect legal targets, but a copy cannot choose different modes or pay a different X.
CASE / 05 · Everything survives
Flayer of Loyalties
can multiply both the cast trigger and the permanent spell. is nonlegendary, so all resolving spell copies can remain as token bodies.
CASE / 06 · Triggers stay; legends collide
Ulamog, the Ceaseless Hunger
Every copied cast trigger still exiles two permanents. Copied Ulamog spells resolve as tokens, but state-based actions force all but one legendary Ulamog under your control to leave.
CASE / 07 · Eldrazi, but not colorless
Crib Swap
Changeling makes an Eldrazi spell, so and see it. Its white mana symbol means does not copy the spell directly—although still doubles 's trigger.
ENGINE BOUNDARIES
Colorless and Eldrazi are different questions.
The card type and the card's color determine which triggers appear. Check both before building the stack.

copies it. and do not trigger from it.
Devoid makes it colorless for , but it has no Eldrazi type for .
Copies are not cast.
No copied spell retriggers or a “when you cast this spell” ability. Only the original cast starts those abilities.
Choices mostly stay locked.
Modes, X, kicker status, and other additional-cost results carry into a spell copy. Legal targets may be changed when the effect permits it.
The stack is the snapshot.
copies only spells and abilities still waiting when its trigger resolves. Resolve the valuable trigger too early and it is gone.
Permanent copies become tokens.
They enter as token copies but are not considered “created.” Legendary copies still meet the legend rule immediately afterward.
Every checkpoint is interruptible.
Players receive priority between resolving objects. Announce the stack order and each {C}{C} payment; opponents can respond before the next object resolves.

PILOT NOTES / KEEP VISIBLEFour truths
Four truths
before launch.
{C}{C} is not generic mana.
Protect access to true colorless sources. A five-color land base can still fail if every source only makes colored mana.
Legendary copies are mostly trigger machines.
separately copies the cast-trigger abilities already waiting on the stack; copied Ulamog or spells are not cast again, and duplicate legendary permanents will not remain together.
Do not expose every engine at once.
One reducer plus one copy engine is enough to demand an answer. Keep the second wave in hand and force the table to solve the deck twice.
Set expectations before the first cast.
This is upgraded, cast-trigger Eldrazi—not an infinite-combo deck. Annihilator and targeted land exile are still sharp tools, so tell the table what kind of void is arriving.
