How it works
Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.
Cast Damage Control Crew by paying its mana cost.
When Damage Control Crew enters the battlefield, it triggers, returning Walk the Aeons from your graveyard to your hand.
Move to your next turn.
Activate Dour Port-Mage by paying 1 and tapping it, returning Damage Control Crew from the battlefield to your hand.
Dour Port-Mage triggers, causing you to draw a card.
Repeat.
This clever loop feeds on the recursive synergy between Damage Control Crew and Walk the Aeons, using the former's enter-the-battlefield ability to continuously buy back the extra turn spell from your graveyard. To keep the engine running, Dour Port-Mage plays a double role: its activated ability bounces Damage Control Crew back to your hand so it can be recast, and its static triggered ability rewards that bounce by letting you draw a card every time the Crew leaves the battlefield without dying.
