Dour Port-Mage + Temporal Manipulation + Damage Control Crew

Dour Port-Mage

Temporal Manipulation

Damage Control Crew

How it works

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

This ingenious loop lets you command infinite turns while continuously digging through your deck. By using Temporal Manipulation to grant yourself consecutive turns, you set up a recurring engine where Damage Control Crew enters the battlefield and uses its Repair mode to fish Temporal Manipulation right back out of your graveyard. Meanwhile, Dour Port-Mage plays a double role: its activated ability bounces Damage Control Crew safely back to your hand for re-casting, and its triggered ability rewards that bounce by drawing you a card every single iteration.
