Cast Temporal Manipulation by paying its mana cost, causing you to take an extra turn after this one.
Cast Ghostly Flicker by paying 2, blinking Mystic Sanctuary and Returned Pastcaller.
When Returned Pastcaller and Mystic Sanctuary enter the battlefield, they trigger.
Resolve the Returned Pastcaller trigger, returning Ghostly Flicker from your graveyard to your hand.
Resolve the Mystic Sanctuary trigger, putting Temporal Manipulation from your graveyard onto the top of your library.
Move to your next turn, drawing Temporal Manipulation during your draw step.
Repeat.
This elegant loop locks down the game by chaining infinite turns, fueled entirely by the recursive power of Ghostly Flicker. By casting Temporal Manipulation, you secure the extra time you need, while Returned Pastcaller safely plucks Ghostly Flicker back to your hand as it enters the battlefield. Simultaneously, the clever design of Mystic Sanctuary allows it to constantly reset Temporal Manipulation to the top of your library, ensuring you draw it reliably on your next turn. Together, this harmonious sequence lets you manipulate time indefinitely, leaving your opponents with no room to act.
