Morophon, the Boundless naming Human reduces Saffi Eriksdotter to free, which is the axis the whole loop turns on. Saffi targets Eternal Witness before dying to Carrion Feeder; Witness returns Saffi to hand on ETB, Saffi casts for nothing, and the cycle repeats indefinitely while Carrion Feeder grows without limit. This is a 5-color Humans shell payoff — the pieces are individually useful, so the combo rarely sits dead in hand.

Recipe

How it works

Prerequisites

"Human" or "Scout" chosen with Morophon.

Steps

Activate Saffi by sacrificing it, targeting Eternal Witness.
Activate Carrion Feeder by sacrificing Eternal Witness.
When Eternal Witness dies, Saffi triggers, returning Eternal Witness from your graveyard to the battlefield.
When Eternal Witness enters the battlefield, it triggers, returning Saffi from your graveyard to your hand.
Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
Cast Saffi by paying due to Morophon.
Repeat.

Result

Infinite +1/+1 counters on a creature; Infinite death triggers; Infinite ETB; Infinite LTB; Infinite sacrifice triggers; Infinite storm count

Variations

Cheaper, tighter, alternate lines

Viscera Seer replaces Carrion Feeder if infinite scry is more useful than counters in a given build, since it also costs 1 and eats creatures for free. Any infinite-death payoff closes the game here — Impact Tremors, Altar of Dementia, or Blood Artist all convert the loop without adding combo pieces. Drop to a tighter line if the table is removal-heavy; Saffi dying to a Lightning Bolt mid-activation collapses the whole sequence.
