Wheel of Sun and Moon + Leveler + Time Warp

Wheel of Sun and Moon

Leveler

Time Warp

How it works

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

By enchanting yourself with Wheel of Sun and Moon, you completely rewrite the destination of any card heading to your graveyard, turning your library into a self-sustaining loop. When you drop Leveler onto the battlefield, its devastating enter-the-battlefield trigger exiles your entire library—a normally fatal drawback that this enchantment turns into an absolute advantage. With your library entirely empty, every sorcery you cast becomes instantly repeatable; when you cast Time Warp to secure an extra turn, Wheel of Sun and Moon ensures it bypasses the graveyard entirely and goes straight to the bottom of your library. Since your library contains only that single card, you simply draw Time Warp on your next turn, cast it again, and chain infinite turns together indefinitely.
