Progenitor Mimic + Capture of Jingzhou + Revolutionist

Progenitor Mimic

Capture of Jingzhou

Revolutionist

How it works

1. Cast Capture of Jingzhou by paying its mana cost, taking an extra turn after this one.
2. At the beginning of your next upkeep, Progenitor Mimic triggers, creating a token copy of Revolutionist.
3. When the token Revolutionist enters the battlefield, it triggers itself, returning Capture of Jingzhou from your graveyard to your hand.
4. Repeat.

This elegant loop centers on the recursive power of Revolutionist and Progenitor Mimic working in tandem. By having the Mimic enter as a copy of the Revolutionist, it sets up a recurring engine that triggers at the start of every upkeep to pull Capture of Jingzhou right back out of your graveyard and into your hand. Because Capture of Jingzhou grants you an immediate extra turn, you keep marching relentlessly through infinite upkeeps, constantly feeding the Mimic token and locking down the game in your favor.
