Dour Port-Mage + Shipwreck Dowser + Walk the Aeons

Dour Port-Mage

Shipwreck Dowser

Walk the Aeons

How it works

1. Cast Walk the Aeons 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 Walk the Aeons 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 clever loop lets you take infinite turns by endlessly recycling your win condition using Shipwreck Dowser to fish Walk the Aeons back out of your graveyard every time it's cast. To keep the chain flowing without running out of resources, Dour Port-Mage plays a double role: its activated ability bounces Shipwreck Dowser back to your hand so it can be replayed, while its passive triggered ability rewards you with a fresh card draw each time a creature leaves the battlefield without dying.
