Progenitor Mimic + Temporal Manipulation + Pinnacle Monk // Mystic Peak

Progenitor Mimic

Temporal Manipulation

Pinnacle Monk // Mystic Peak

How it works

1. Cast Temporal Manipulation by paying 3, causing you to take an extra turn after this one.
2. At the beginning of your next upkeep, Progenitor Mimic triggers, creating a token copy of Pinnacle Monk.
3. When the token Pinnacle Monk enters the battlefield, it triggers, returning Temporal Manipulation from your graveyard to your hand.
4. Repeat.

This brilliant loop hinges on the clever recursion enabled by Pinnacle Monk // Mystic Peak's entrance trigger, which plucks Temporal Manipulation right back out of your graveyard and into your hand after you cast it. To sustain this sequence indefinitely, Progenitor Mimic steps in by perpetually spawning a fresh token copy of the Monk at the start of each upkeep, ensuring you always have a fresh entry trigger waiting for you. Because Progenitor Mimic's upkeep trigger only fires if the original creature isn't a token, the non-token copy you create acts as a permanent factory that feeds your chain of extra turns.
