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 Skullwinder.
When Skullwinder and Mystic Sanctuary enter the battlefield, they trigger.
Resolve the Skullwinder 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 brilliant loop locks down the game by granting you infinite turns, entirely fueled by the clever recursion of Temporal Manipulation. By casting Ghostly Flicker, you reset both Skullwinder—whose entry trigger continuously loops Ghostly Flicker back to your hand—and Mystic Sanctuary, which leverages its own untapped entry condition to place Temporal Manipulation right back on top of your library to be drawn on your next turn.
