Progenitor Mimic + Capture of Jingzhou + Greenwarden of Murasa

Progenitor Mimic

Capture of Jingzhou

Greenwarden of Murasa

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 Greenwarden of Murasa.
3. When the token Greenwarden of Murasa enters the battlefield, it triggers itself, returning Capture of Jingzhou from your graveyard to your hand.
4. Repeat.

This brilliant setup creates an endless engine of recurring time magic by leaning on the steady rhythm of your upkeep. When Progenitor Mimic is copying Greenwarden of Murasa, its non-token restriction doesn't apply to the copies it churns out, allowing a fresh Greenwarden of Murasa token to materialize at the start of every single turn. Each time that token arrives, its triggered ability plucks Capture of Jingzhou right back out of your graveyard and into your hand, ready to be cast again to secure your next extra turn. Because the original Greenwarden of Murasa stays safely on the board as the template, this cycle repeats indefinitely to lock down the game with limitless turns.
