Karn's Bastion proliferates to add a charge counter to Lost Jitte and grow Cryptic Trilobite; the Trilobite cashes two +1/+1 counters for four colorless, and Lost Jitte spends one charge counter to untap the land and restart the loop. The engine asks nothing of the combat step and sits entirely in the activated-ability space, so it runs cleanly under most stax pieces that hate on spells.

Recipe

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

Variations

Cheaper, tighter, alternate lines

The loop requires all four pieces and specific starting counters on two of them, so it assembles slowly without dedicated tutors — Eldritch Evolution and Finale of Devastation find the creatures, but Lost Jitte and Karn's Bastion need their own lines. Once infinite proliferate is live, the win condition depends entirely on what already has counters on the board; pair this with Vorinclex, Monstrous Raider, Walking Ballista, or a planeswalker one tick from ultimate to close the game.
