Mystic Sanctuary + Dust Bowl + Temporal Manipulation + Ancient Greenwarden

Mystic Sanctuary

Dust Bowl

Temporal Manipulation

Ancient Greenwarden

How it works

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

This ingenious loop hinges on Ancient Greenwarden's ability to let you play lands straight from your graveyard while doubling land-based triggered abilities. By utilizing Dust Bowl's activation to sacrifice Mystic Sanctuary, you clear the way to immediately replay Mystic Sanctuary from your graveyard. Thanks to Ancient Greenwarden, Mystic Sanctuary's entry triggers twice, allowing you to seamlessly recycle Temporal Manipulation from your graveyard right back to the top of your library so you can draw and cast it on your endless extra turns.
