Wheel of Sun and Moon + Phyrexian Devourer + Time Warp

Wheel of Sun and Moon

Phyrexian Devourer

Time Warp

How it works

1. Activate Phyrexian Devourer by exiling the top card of your library.
2. Repeat step 1 until you have an empty library.
3. Resolve the first Phyrexian Devourer ability, putting a number of +1/+1 counters on it.
4. If Phyrexian Devourer's power is at least seven, it triggers, causing you to sacrifice it.
5. Repeat from step 3 for each remaining trigger.
6. 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.
7. Move to your next turn, drawing Time Warp from your library.
8. Repeat from step 6.

This ingenious loop turns Phyrexian Devourer into a self-consuming engine that completely empties your library by exiling every card within it. Normally, losing your library means doom, but Wheel of Sun and Moon intercepts any card headed to your graveyard—including spells like Time Warp—and safely tucks them back onto the bottom of your library instead. Because your library is otherwise entirely empty, drawing for your turn will always yield that exact same Time Warp, allowing you to cast it, trigger Wheel of Sun and Moon to reset it, and take infinite turns to dominate the game.
