Karn's Bastion proliferates onto Lost Jitte and Cryptic Trilobite; Corpsejack Menace doubles the two +1/+1 counters Trilobite receives into four, giving it the fuel to produce the four colorless needed to untap Bastion via Lost Jitte's charge-counter removal. The loop is colorless-mana-gated once assembled — Trilobite's ability only spends toward activated abilities, which is exactly what Karn's Bastion and Lost Jitte demand. Any proliferate payoff already on the battlefield, from Atraxa, Praetors' Voice to Ozolith, the Shattered Spire, converts the chain into a win.

How it works

Prerequisites

Lost Jitte has at least one charge counter on it. Cryptic Trilobite has at least one +1/+1 counter on it.

Steps

Activate Karn's Bastion by paying , putting a charge counter on Lost Jitte and two +1/+1 counters on Cryptic Trilobite.
Activate Cryptic Trilobite's first ability twice by removing two +1/+1 counters from it, adding that can only be spent to activate abilities.
Activate Lost Jitte by removing a charge counter from it, untapping Karn's Bastion.
Repeat.

Result

Infinite proliferate

Cheaper, tighter, alternate lines

Corpsejack Menace is the hardest piece to replace here — Doubling Season and Vorinclex, Monstrous Raider also double counters and can substitute, though both demand significantly more setup mana to land. The loop produces infinite proliferate but no direct damage or draw on its own; pair it with a Walking Ballista already in play, or a planeswalker at ultimate threshold, to close the game immediately.
