Deadbridge Chant + Tormod's Crypt + Capture of Jingzhou

Deadbridge Chant

Tormod's Crypt

Capture of Jingzhou

How it works

1. Activate Tormod's Crpyt by tapping and sacrificing it, exiling your graveyard.
2. Cast Capture of Jingzhou by paying 3, causing you to take an extra turn after this one.
3. Move to your next turn.
4. At the beginning of your upkeep, Deadbridge Chant triggers, returning Capture of Jingzhou to your hand from your graveyard.
5. Repeat from step 2.
6. NOTE: This combo can fail if other cards enter your graveyard after step 1.

This ingenious loop leverages the precise control of Tormod's Crypt to empty your graveyard, ensuring that Deadbridge Chant's upkeep trigger has only one possible target to select. By purging everything else away, the random selection hits the newly cast and resolved Capture of Jingzhou every single time, returning the sorcery directly to your hand. This sets up a perpetual motion machine of extra turns, provided no outside interference clutters your graveyard in the meantime.
