Dour Port-Mage + Warden of the Eye + Time Warp

Dour Port-Mage

Warden of the Eye

Time Warp

How it works

1. Cast Time Warp 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 Time Warp 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 sets up a self-sustaining loop of endless time by repeatedly leveraging Dour Port-Mage alongside Warden of the Eye to endlessly recycle Time Warp. Once you have managed to cast Time Warp to secure your extra turns, every subsequent loop lets Warden of the Eye pluck it right back out of your graveyard as it enters the battlefield. Meanwhile, the activated ability of Dour Port-Mage safely bounces Warden of the Eye back to your hand for the next iteration, while its passive triggered ability rewards your board's movement by netting you an extra card draw every single cycle.
