Mystic Sanctuary + Dust Bowl + Ramunap Excavator + Time Warp

Mystic Sanctuary

Dust Bowl

Ramunap Excavator

Time Warp

How it works

1. Cast Time Warp by paying its mana cost, causing you to take an extra turn after this one.
2. Activate Dust Bowl by paying 3, tapping it and sacrificing Mystic Sanctuary, destroying a nonbasic land.
3. Play Mystic Sanctuary from your graveyard.
4. When Mystic Sanctuary enters untapped, it triggers, putting Time Warp from your graveyard onto the top of your library.
5. Move to your next turn, drawing Time Warp during your draw step.
6. Repeat.

This intricate sequence harnesses the recursive engine of Ramunap Excavator to strip away your opponents' manabases with Dust Bowl while simultaneously locking down infinite turns. By casting Time Warp, you secure the extra time needed to continuously manipulate the battlefield, letting you sacrifice Mystic Sanctuary to the Dust Bowl loop and replay it straight from your graveyard. Because Mystic Sanctuary enters the battlefield untapped when you control enough Islands, its triggered ability lets you fish Time Warp right back off the top of your library to cast it all over again.
