Extravagant Replication triggers at the beginning of each upkeep, copying Eternal Witness and returning Walk the Aeons from the graveyard to hand; the extra turn from Walk the Aeons feeds the next upkeep trigger, and the loop sustains itself. The combo lives in Simic value shells — Rashmi, Eternities Crafter, Aesi, Tyrant of Gyre Strait, or any blue-green commander that wants enchantments and recursion in the same 99.

How it works

Prerequisites

You have enough mana to cast Walk the Aeons each turn.

Steps

Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.
Move to your next turn.
At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Eternal Witness.
When the Eternal Witness token enters the battlefield, it triggers, returning Walk the Aeons from your graveyard to your hand.
Repeat.

Result

Infinite turns; Lock

Cheaper, tighter, alternate lines

Archaeomancer and Salvager of Secrets both replace Eternal Witness as the graveyard retrieval piece if Witness is exiled. The loop demands mana to recast Walk the Aeons each iteration — 3UU every turn — so Seedborn Muse or mana doublers like Vorinclex, Voice of Hunger are natural companions to keep the engine running indefinitely.
