Mystic Sanctuary

Dust Bowl

Time Warp

Szarel, Genesis Shepherd

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.
