This clever loop turns total self-exile into an engine for infinite turns by cleverly manipulating your own library. When you cast Leveler, its enters-the-battlefield trigger wipes out your library entirely, leaving a blank slate where Wheel of Sun and Moon can go to work. By enchanting yourself with Wheel of Sun and Moon, any card that would hit your graveyard instead goes straight to the bottom of your library—which means when you cast Walk the Aeons, the replacement effect smoothly recycles it right back into your deck. You simply draw it on your extra turn, repeat the process, and lock down the game with endless actions.
