Progenitor Mimic + Temporal Manipulation + Ardent Elementalist

Progenitor Mimic

Temporal Manipulation

Ardent Elementalist

How it works

1. Cast Temporal Manipulation 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 Ardent Elementalist.
3. When the token Ardent Elementalist enters the battlefield, it triggers itself, returning Temporal Manipulation from your graveyard to your hand.
4. Repeat.

This elegant loop achieves infinite turns by recycling a single copy spell through continuous entry triggers. **Temporal Manipulation** provides the extra turns you need, while **Ardent Elementalist** acts as your recovery engine by pulling that spell right back out of the graveyard every time she arrives. The true brilliance of the engine lies in **Progenitor Mimic**, which bypasses normal casting restrictions by churning out a fresh token copy of the **Ardent Elementalist** at the start of every single upkeep, effortlessly sustaining the infinite loop turn after turn.
