Progenitor Mimic + Revolutionist + Time Warp

Progenitor Mimic

Revolutionist

Time Warp

How it works

1. Cast Time Warp 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 Time Warp from your graveyard to your hand.
4. Repeat.

This elegant loop leverages Progenitor Mimic as a tireless copy machine, targeting Revolutionist to endlessly recur spells from your graveyard. Because Progenitor Mimic is not a token itself, its upkeep trigger reliably spawns a new Revolutionist token every single turn, which immediately triggers its ability to fish Time Warp right back out of your graveyard into your hand. Replaying Time Warp then grants you the extra turn needed to arrive at your next upkeep, locking down the game in an unstoppable succession of infinite turns.
