Karn's Bastion proliferates to stack Lost Jitte and Cryptic Trilobite simultaneously; Trilobite cashes two of its new +1/+1 counters for four restricted mana, and Lost Jitte spends a charge counter to untap the Bastion and reset the loop. The engine is colorless at its core but lives in green counter-based shells — Atraxa, Praetors' Voice and Ezuri, Claw of Progress are the natural homes.

Recipe

How it works

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

Variations

Cheaper, tighter, alternate lines

Ozolith, the Shattered Spire isn't listed as a combo piece but sits in the same shell to preserve counters across removal; if Cryptic Trilobite dies mid-loop, the chain collapses. The loop wins through whatever counters are already on board — poison counters close the game under Atraxa, experience counters snowball Ezuri, or Walking Ballista drains out the table once mana is freed from Trilobite's restriction.
