Ghostly Flicker + Mystic Sanctuary + Time Walk + Timeless Witness

Ghostly Flicker

Mystic Sanctuary

Time Walk

Timeless Witness

How it works

1. Activate Mystic Sanctuary by tapping it, adding .
2. Cast Time Walk by paying its mana cost, causing you to take an extra turn after this one.
3. Cast Ghostly Flicker by paying 2, blinking Mystic Sanctuary and Timeless Witness.
4. When Timeless Witness and Mystic Sanctuary enter the battlefield, they trigger.
5. Resolve the Timeless Witness trigger, returning Ghostly Flicker from your graveyard to your hand.
6. Resolve the Mystic Sanctuary trigger, putting Time Walk from your graveyard onto the top of your library.
7. Move to your next turn, drawing Time Walk during your draw step.
8. Repeat.

This classic Vintage loop gives you infinite turns by chaining Time Walk over and over again, locking your opponent out of the game entirely. Ghostly Flicker serves as the engine, resetting both Mystic Sanctuary—which ensures Time Walk always returns straight to the top of your library—and Timeless Witness, whose entry trigger fishes Ghostly Flicker right back out of your graveyard.
