Wheel of Sun and Moon + Leveler + Temporal Manipulation

Wheel of Sun and Moon

Leveler

Temporal Manipulation

How it works

1. Cast Leveler by paying 5.
2. When Leveler enters the battlefield, it triggers, exiling your library.
3. Cast Temporal Manipulation by paying 3, causing you to take an extra turn after this one, and put Temporal Manipulation on the bottom of your library due to Wheel of Sun and Moon.
4. Move to your next turn, drawing Temporal Manipulation from your library.
5. Repeat from step 3.

This mind-bending loop exploits the replacement effect of Wheel of Sun and Moon placed on yourself, ensuring that whenever a card would hit your graveyard, it gets tucked safely on the bottom of your library instead. Once Leveler enters the battlefield to instantly exile your entire library, your deck shrinks down to a single-card ecosystem. You then cast Temporal Manipulation to take an extra turn, and thanks to the Wheel, that very same spell goes straight to the bottom of your library rather than your graveyard. When your next turn begins, you simply draw Temporal Manipulation again, casting it indefinitely to lock the game into a relentless sequence of infinite turns.
