Progenitor Mimic + Greenwarden of Murasa + Notorious Throng

Progenitor Mimic

Greenwarden of Murasa

Notorious Throng

How it works

1. Deal combat damage to an opponent using a Rogue.
2. Cast Notorious Throng for its prowl cost by paying 5, causing you to take an extra turn after this one.
3. At the beginning of your next upkeep, Progenitor Mimic triggers, creating a token copy of Greenwarden of Murasa.
4. When the Greenwarden of Murasa token enters the battlefield, it triggers, returning Notorious Throng from your graveyard to your hand.
5. Repeat.

This dazzling loop lets you chain together infinite turns by combining an extra-turn payoff with a repeating recursion engine. You start by casting Notorious Throng for its prowl cost, taking an extra turn while setting the sorcery safely into your graveyard. At the dawn of that extra turn, Progenitor Mimic's upkeep trigger conjures a fresh token copy of Greenwarden of Murasa, whose enters-the-battlefield ability immediately plucks Notorious Throng back from your graveyard into your hand. Because the token is not a non-token creature, Progenitor Mimic continues to pump out a new Greenwarden of Murasa every single upkeep, letting you recast the same Notorious Throng indefinitely.
