Mystic Sanctuary + Dust Bowl + Walk the Aeons + Szarel, Genesis Shepherd

Mystic Sanctuary

Dust Bowl

Walk the Aeons

Szarel, Genesis Shepherd

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 ingenious loop grants you near-infinite turns by continually recycling a single copy of Walk the Aeons. Szarel, Genesis Shepherd is the linchpin that makes it all possible, allowing you to replay lands directly from your graveyard—specifically enabling you to redeploy Mystic Sanctuary after it falls to Dust Bowl's sacrifice cost. Every time Mystic Sanctuary enters the battlefield untapped, its triggered ability places Walk the Aeons right back on top of your library to be drawn on your next turn, creating an unbreakable temporal lock.
