Mystic Sanctuary + Dust Bowl + Time Walk + Conduit of Worlds

Mystic Sanctuary

Dust Bowl

Time Walk

Conduit of Worlds

How it works

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

By chaining Time Walk into a perpetual sequence of extra turns, this Vintage-legal setup achieves a total lock on the game. The engine relies on Conduit of Worlds to let you play lands from your graveyard, specifically recycling Mystic Sanctuary so that its landfall-like trigger continuously places Time Walk right back on top of your library. Meanwhile, Dust Bowl plays the crucial role of a repeatable sacrifice outlet that allows you to bin Mystic Sanctuary each turn so it can be replayed and re-triggered.
