Dour Port-Mage + Skullwinder + Temporal Manipulation

Dour Port-Mage

Skullwinder

Temporal Manipulation

How it works

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

This elegant engine relies on Dour Port-Mage to act as both the engine's bouncer and its card-draw reward, using its activated ability to return Skullwinder to your hand at instant speed. Each time Skullwinder re-enters the battlefield, its triggered ability loops Temporal Manipulation right back from your graveyard to your hand, securing an infinite sequence of extra turns. Meanwhile, Dour Port-Mage's passive triggered ability rewards you with a card every single time Skullwinder leaves the battlefield without dying, turning your infinite loop into a deep resource advantage.
