Emptiness evoked for

sets up a chain where Phyrexian Altar sacrifices it in response to the evoke trigger, banking

while still resolving the enters trigger to return Eternal Witness from the graveyard. Eternal Witness then retrieves Emptiness from the bin, Phyrexian Altar sacrifices the Witness for another

, and the loop restarts — self-funding on the sacrifice mana once the engine is running. The table sees no interaction window once the loop begins, and any commander that cares about ETBs, death triggers, or sacrifices closes the game immediately.

Cheaper, tighter, alternate lines

Karmic Guide can replace Eternal Witness as the recursion piece, functioning identically in the loop but requiring white instead of green. Pair the infinite triggers with Impact Tremors, Altar of Dementia, or Blood Artist as the kill — the loop produces no direct damage or mill on its own, so the closer must already be on the battlefield before the chain starts.
