Soulherder blinks Eternal Witness at end of turn; Eternal Witness returns Walk the Aeons to hand, and the loop restarts with the next extra turn. The engine asks for nothing beyond its three pieces — no mana sink, no additional enabler — which is exactly what makes it dangerous in Bant flicker shells like Roon of the Hidden Realm or Brago, King Eternal.

Recipe

How it works

Prerequisites

Steps

With Soulherder and a creature based spell recursion effect on the battlefield, cast the extra turn spell.
Move to end step and target the creature with Soulherder's ability.
When creature re-enters the battlefield, target the extra turn spell in your graveyard and return it to your hand, then pass to yourself.
Repeat

Result

Infinite turns; Lock

Variations

Cheaper, tighter, alternate lines

Conjurer's Closet or Erratic Portal can substitute for Soulherder as the blink engine if needed, though both require more setup mana each cycle. Strionic Resonator can copy Eternal Witness's ETB trigger to retrieve a second target if disruption splits the graveyard mid-loop — but the tightest build runs the three pieces as listed and wins on the first resolved Walk the Aeons.
