Mystic Sanctuary + Dust Bowl + Capture of Jingzhou + Conduit of Worlds

Mystic Sanctuary

Dust Bowl

Capture of Jingzhou

Conduit of Worlds

How it works

1. Cast Capture of Jingzhou 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 Capture of Jingzhou from your graveyard onto the top of your library.
5. Move to your next turn, drawing Capture of Jingzhou during your draw step.
6. Repeat.

This ingenious loop achieves near-infinite turns by recycling a single copy of Capture of Jingzhou through your library and graveyard over and over again. The engine is made possible by Conduit of Worlds, which lets you play lands directly from your graveyard so you can constantly redeploy Mystic Sanctuary. Every time Mystic Sanctuary enters the battlefield untapped, its triggered ability places Capture of Jingzhou right back on top of your library to be drawn on your next turn. Meanwhile, Dust Bowl plays the crucial role of sacrificing Mystic Sanctuary to send it back to the graveyard in the first place, ensuring the land drop is always ready to be replayed.
