This brilliant combination locks down the game by chaining infinite turns, fueled entirely by recycling your graveyard. Every piece plays a crucial role: **Time Stretch** grants you the extra turns you need, while **Ghostly Flicker** resets the permanents that make the loop possible. By blinking **Returned Pastcaller**, you retrieve the flicker spell back to your hand, and simultaneously blinking **Mystic Sanctuary** triggers its land ability to place **Time Stretch** right back on top of your library for your next draw step.
