Notorious Throng's prowl trigger grants an extra turn and hits the graveyard; Eternal Witness enters to return it, then Dour Port-Mage bounces Eternal Witness back to hand and draws a card to fuel the next iteration. The setup demands an unblockable Rogue already in play — something like Invisible Stalker or a ninjutsu-enabled attacker — which means this combo fits naturally into a Yuriko, the Tiger's Shadow or rogues-tribal shell that already wants that infrastructure.

How it works

Prerequisites

You control a Rogue that does not have summoning sickness and that cannot be blocked by an opponent.

Steps

Deal combat damage to an opponent using a Rogue.
Cast Notorious Throng for its prowl cost by paying , causing you to take an extra turn after this one.
Cast Eternal Witness by paying its mana cost.
When Eternal Witness enters the battlefield, it triggers, returning Notorious Throng from your graveyard to your hand.
Move to your next turn.
Activate Dour Port-Mage by paying and tapping it, returning Eternal Witness from the battlefield to your hand.
Dour Port-Mage triggers, causing you to draw a card.
Repeat.

Result

Infinite turns; Lock

Cheaper, tighter, alternate lines

Any creature with a enters-the-battlefield trigger that returns a card from the graveyard can fill the Eternal Witness slot — Timeless Witness functions identically and has the same mana cost. The combo locks the table the moment the loop begins, but it folds to any instant-speed removal on Dour Port-Mage or Eternal Witness during the activation window, so blue protection like Slip Out the Back is worth running as insurance.
