Dour Port-Mage + Temporal Manipulation + Archaeomancer

Dour Port-Mage

Temporal Manipulation

Archaeomancer

How it works

1. Cast Temporal Manipulation by paying its mana cost, causing you to take an extra turn after this one.
2. Cast Archaeomancer by paying its mana cost.
3. When Archaeomancer 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 Archaeomancer from the battlefield to your hand.
6. Dour Port-Mage triggers, causing you to draw a card.
7. Repeat.

This charming loop gives you infinite turns by recycling a single spell through clever creature choreography. When you cast Temporal Manipulation to secure an extra turn, Archaeomancer follows close behind to fish the sorcery right back out of your graveyard as it enters the battlefield. From there, Dour Port-Mage steps in as both the engine and the reward: by tapping to activate its ability, it bounces Archaeomancer back to your hand so you can replay it, while its static triggered ability simultaneously rewards your hand-bouncing efforts by letting you draw a card every single time.
