This elegant Vintage loop locks down the game by chaining endless extra turns with Eternal Witness and Followed Footsteps. Each upkeep, the Aura creates a fresh copy of Eternal Witness to trigger its enters-the-battlefield ability, reaching into your graveyard to retrieve Time Walk so you can cast it again. Because Time Walk grants you an entire sequence of extra turns, your token army and spellcasting cycle can repeat indefinitely until your opponents are completely buried.
