Phantom Steed's attack trigger creates a tapped, attacking token copy of Eternal Witness, which immediately returns Walk the Aeons from the graveyard to hand — ready to cast again next turn. The combo lives in Simic extra-turns shells, typically helmed by commanders like Saber Kami or anything that grants evasion, since the entire loop collapses the moment Phantom Steed gets chump blocked.

Cheaper, tighter, alternate lines

Archaeomancer and Mnemonic Wall perform the same Walk the Aeons recursion if Eternal Witness is removed from the equation, though both require the full tap trigger rather than a combat ETB. Strionic Resonator can copy Phantom Steed's triggered ability to generate multiple Witness tokens in one attack, insulating the loop against a single token being killed before its ETB resolves.
