Karn's Bastion proliferates each loop, stacking counters on every permanent that already has one; Lost Jitte untaps the Bastion for free by cashing a charge counter, and Cryptic Trilobite converts its two freshly proliferated +1/+1 counters into the four colorless needed to activate Karn's Bastion again. The Earth Crystal is the glue — it grants Karn's Bastion the proliferate ability, making the whole chain possible. This belongs in any green counters-matter shell running commanders like Atraxa, Praetors' Voice or Ozolith, the Shattered Spire.

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

The loop requires all four pieces and both prerequisite counters to already be in place, so consistent tutoring — Crop Rotation for Karn's Bastion, Enlightened Tutor for Lost Jitte — matters. Infinite proliferate wins on the spot with a single planeswalker near its ultimate, a Walking Ballista already on board, or any poison counter sitting on an opponent; without a pre-existing payoff, the loop generates value but not an immediate kill.
