Mystic Sanctuary + Dust Bowl + Crucible of Worlds + Walk the Aeons

Mystic Sanctuary

Dust Bowl

Crucible of Worlds

Walk the Aeons

How it works

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

This loop achieves near-infinite turns by leveraging Crucible of Worlds to constantly replay lands from your graveyard, turning Dust Bowl into a recurring engine to feed Mystic Sanctuary back onto the battlefield. Because you are playing Mystic Sanctuary while controlling enough Islands to bypass its restriction, its triggered ability immediately puts Walk the Aeons from your graveyard back on top of your library to be drawn on your next turn. This self-sustaining cycle lets you chain extra turns indefinitely, locking out your opponents while Dust Bowl systematically strips away their nonbasic lands.
