Dour Port-Mage + Warden of the Eye + Walk the Aeons

Dour Port-Mage

Warden of the Eye

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 Warden of the Eye by paying its mana cost.
3. When Warden of the Eye 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 Warden of the Eye from the battlefield to your hand.
6. Dour Port-Mage triggers, causing you to draw a card.
7. Repeat.

This brilliant engine achieves infinite turns by recycling Walk the Aeons over and over again from your graveyard straight back to your hand. When you cast Warden of the Eye, its enters-the-battlefield ability triggers to retrieve that extra-turn spell for you. From there, Dour Port-Mage steps in as the engine's trusty anchor; by paying its activation cost to bounce Warden of the Eye back to your hand, Dour Port-Mage's static-like triggered ability rewards your trouble by drawing you a card every time a creature leaves without dying. Replaying Warden of the Eye restarts the whole loop, letting you take all the time in the world while continuously thinning your deck.
