Dour Port-Mage + Time Walk + Greenwarden of Murasa

Dour Port-Mage

Time Walk

Greenwarden of Murasa

How it works

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

This clever Vintage-legal engine achieves infinite turns by recycling Time Walk through a perpetual cycle of bouncing and recasting. Each iteration is fueled by casting Greenwarden of Murasa, whose entry trigger plucks Time Walk right back from your graveyard into your hand. To keep the loop going, Dour Port-Mage uses its activated ability to return Greenwarden of Murasa safely to your hand while simultaneously triggering its own passive draw ability to net you an extra card every single turn.
