Dour Port-Mage + Scholar of the Ages + Time Warp

Dour Port-Mage

Scholar of the Ages

Time Warp

How it works

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

This elegant loop centers on the recursive power of Scholar of the Ages, which perpetually reclaims Time Warp from your graveyard every time it hits the battlefield so you can string together endless extra turns. To keep the engine running, Dour Port-Mage pulls double duty: its activated ability bounces the Scholar back to your hand for replay, while its static triggered ability rewards that departure by letting you draw a card every time the Scholar leaves the battlefield without dying.
