Dour Port-Mage + Returned Pastcaller + Time Warp

Dour Port-Mage

Returned Pastcaller

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

This clever engine centers around Returned Pastcaller, which provides the crucial recursion by pulling Time Warp back from your graveyard straight into your hand the moment it enters the battlefield. To reset this loop, Dour Port-Mage steps in with its activated ability, bouncing Returned Pastcaller back to your hand so you can recast it on your next extra turn. Meanwhile, Dour Port-Mage's passive triggered ability rewards you for this constant bouncing by drawing you an extra card every single time Returned Pastcaller leaves the battlefield without dying, turning your infinite turn lock into a fully stocked hand as well.
