Cast Notorious Throng 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 Notorious Throng from your graveyard onto the top of your library.
Move to your next turn, drawing Notorious Throng during your draw step.
Repeat.
This elegant loop lets you chain together infinite turns by continually recycling your spells and lands right back into play. You start by casting Notorious Throng—optimizing its prowl cost after landing a hit with a Rogue—to take an extra turn. From there, Ghostly Flicker comes in to blink both Vampire Charmseeker and Mystic Sanctuary. Vampire Charmseeker's entry trigger fishes Ghostly Flicker right back out of your graveyard, while Mystic Sanctuary's landfall-style ability neatly stacks Notorious Throng back on top of your library to draw and cast on your next consecutive turn.
