Dour Port-Mage + Capture of Jingzhou + Shipwreck Dowser

Dour Port-Mage

Capture of Jingzhou

Shipwreck Dowser

How it works

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

This brilliant extra-turn loop centers around casting Capture of Jingzhou to seize subsequent turns, which is then recurred endlessly by Shipwreck Dowser whenever it enters the battlefield from your hand. To keep the cycle going, Dour Port-Mage provides the necessary bounce using its activated ability to return Shipwreck Dowser to your hand—while simultaneously leveraging its passive triggered ability to net you a card draw every single time Shipwreck Dowser leaves the battlefield without dying.
