Walk the Aeons goes to the graveyard after resolving; Eternal Witness enters and returns it to hand, then Dour Port-Mage pays 1U to bounce the Witness back and draw a card. The loop resets cleanly each extra turn — Witness returns Walk the Aeons, Port-Mage returns Witness, and the table never untaps again. This is the combo for Simic spellslinger or goodstuff builds that already run Eternal Witness as value and want a time-walk finisher attached.

How it works

Prerequisites

available plus enough mana to cast Walk the Aeons and Eternal Witness each turn.

Steps

Cast Walk the Aeons by paying its mana cost, 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 Walk the Aeons 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

Time Warp and Temporal Manipulation are direct Walk the Aeons substitutes at the same converted mana cost without the Island sacrifice requirement, making them easier to recast each loop. Archaeomancer replaces Eternal Witness if the graveyard-to-hand trigger is all that's needed, though it loses the flexibility Witness has outside the combo.
