Ghostly Flicker + Mystic Sanctuary + Archaeomancer + Notorious Throng

Ghostly Flicker

Mystic Sanctuary

Archaeomancer

Notorious Throng

How it works

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

This intricate loop sets up an endless chain of extra turns by chaining together recursion and instant-speed blinking. Once you connect with a Rogue to cast Notorious Throng for its prowl cost, you cast Ghostly Flicker to exile and return both Archaeomancer and Mystic Sanctuary. Archaeomancer's entry trigger brings Ghostly Flicker right back to your hand, while Mystic Sanctuary's untap ability ensures that Notorious Throng is constantly recycled from your graveyard to the top of your library just in time for your next turn's draw step.
