Dour Port-Mage + Temporal Manipulation + Revolutionist

Dour Port-Mage

Temporal Manipulation

Revolutionist

How it works

1. Cast Temporal Manipulation by paying its mana cost, causing you to take an extra turn after this one.
2. Cast Revolutionist by paying its mana cost.
3. When Revolutionist enters the battlefield, it triggers, returning Temporal Manipulation from your graveyard to your hand.
4. Move to your next turn.
5. Activate Dour Port-Mage by paying 1 and tapping it, returning Revolutionist from the battlefield to your hand.
6. Dour Port-Mage triggers, causing you to draw a card.
7. Repeat.

This ingenious loop grants you infinite turns by endlessly recycling your win conditions, anchored by the synergy between Dour Port-Mage and Revolutionist. When you cast Temporal Manipulation for an extra turn, Revolutionist enters the battlefield to fish that very spell right back out of your graveyard. From there, Dour Port-Mage uses its activated ability to bounce Revolutionist back to your hand while simultaneously drawing you a card thanks to its clever static leave-the-battlefield trigger. This leaves Revolutionist ready to be recast on your subsequent turns, completely locking down the game in formats like Commander and Legacy with an unbroken chain of extra turns.
