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 Vampire Charmseeker.
When Vampire Charmseeker and Mystic Sanctuary enter the battlefield, they trigger.
Resolve the Vampire Charmseeker 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 loop locks down the game by chaining infinite turns through perpetual recursion. You kick things off by casting Time Warp to secure an extra turn, while Mystic Sanctuary taps for blue mana and sets up your next draw. The real magic happens when you cast Ghostly Flicker to exile both Mystic Sanctuary and Vampire Charmseeker, blinking them back onto the battlefield. This triggers Vampire Charmseeker to pull Ghostly Flicker right back to your hand, while Mystic Sanctuary tucks Time Warp safely onto the top of your library just in time for your next draw step.
