Chronomantic Escape + Sphinx of the Second Sun + Paradox Haze

Chronomantic Escape

Sphinx of the Second Sun

Paradox Haze

How it works

1. Cast Chronomantic Escape by paying 4, causing creatures to be unable to attack you until your next turn, and exiling Chronomantic Escape with three time counters on it.
2. At the beginning of your postcombat main phase, Sphinx of the Second Sun triggers, causing you to get an additional beginning phase after this phase.
3. Move to your additional beginning phase.
4. At the beginning of your upkeep, Chronomantic Escape triggers, removing a time counter from itself.
5. At the beginning of your next upkeep, Chronomantic Escape and Paradox Haze trigger.
6. Resolve the Paradox Haze trigger, causing you to get an additional upkeep step after this one.
7. Resolve the Chronomantic Escape trigger, removing a time counter from it.
8. Move to your next upkeep step.
9. Chronomantic Escape triggers, removing a time counter from itself and causing you to cast it without paying its mana cost.
10. Resolve Chronomantic Escape, causing creatures to be unable to attack you until your next turn, and exiling Chronomantic Escape with three time counters on it.
11. Repeat from step 2.

This fascinating lock turns the passage of time itself into an impenetrable shield by manipulating extra phases. With Paradox Haze enchanting you and Sphinx of the Second Sun granting additional beginning phases, your turn structure multiplies rapidly to accelerate time counters off Chronomantic Escape. By rapidly burning through those counters via these repeated upkeeps, you can recast Chronomantic Escape for free over and over to ensure that creatures can never attack you again.
