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 Izzet Chronarch.
When Izzet Chronarch and Mystic Sanctuary enter the battlefield, they trigger.
Resolve the Izzet Chronarch 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 mesmerizing loop turns a clever combat entry into an unending succession of time walks, fueled by the recursive synergy of Ghostly Flicker. By targeting both Izzet Chronarch and Mystic Sanctuary with the flicker spell, you trigger a precise sequence: the Chronarch salvages Ghostly Flicker right back to your hand, while the Sanctuary plucks Notorious Throng from your graveyard and nests it neatly on top of your library. When you move into your extra turn, you naturally draw the very spell you need to cast Notorious Throng again, creating an inescapable engine of infinite turns and absolute dominance.
