Cast Time Warp 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 Eternal Witness.
When Eternal Witness and Mystic Sanctuary enter the battlefield, they trigger.
Resolve the Eternal Witness trigger, returning Ghostly Flicker from your graveyard to your hand.
Resolve the Mystic Sanctuary trigger, putting Time Warp from your graveyard onto the top of your library.
Move to your next turn, drawing Time Warp during your draw step.
Repeat.
This brilliant sequence hinges on the recursive power of Ghostly Flicker paired with Eternal Witness to continuously recycle your key spells. By casting Time Warp, you secure the extra turns needed to keep the engine rolling, while Mystic Sanctuary acts as a crucial land piece that leverages your Island count to put Time Warp right back on top of your library for your next draw step. Every card here plays an essential role: Ghostly Flicker provides the repeatable blinking effect, Eternal Witness retrieves your flicker spell from the graveyard, Mystic Sanctuary sets up the next turn's draw, and Time Warp gives you all the time you need to dominate the game entirely.
