Dour Port-Mage + Returned Pastcaller + Capture of Jingzhou

Dour Port-Mage

Returned Pastcaller

Capture of Jingzhou

How it works

1. Cast Capture of Jingzhou by paying its mana cost, causing you to take an extra turn after this one.
2. Cast Returned Pastcaller by paying its mana cost.
3. When Returned Pastcaller enters the battlefield, it triggers, returning Capture of Jingzhou from your graveyard to your hand.
4. Move to your next turn.
5. Activate Dour Port-Mage by paying 1 and tapping it, returning Returned Pastcaller from the battlefield to your hand.
6. Dour Port-Mage triggers, causing you to draw a card.
7. Repeat.

This elegant loop centers on the relentless recursion enabled by Returned Pastcaller, which grabs Capture of Jingzhou out of your graveyard every time it enters the battlefield so you can continuously chain extra turns. To reset this process without spending a fortune in mana, Dour Port-Mage steps in with its activated ability to bounce Returned Pastcaller right back to your hand for reuse, while simultaneously triggering its own passive draw ability to filter through your deck. Once the engine is humming, you not only lock down the game with infinite turns, but you also continuously draw cards to ensure your victory is absolute.
