Deadbridge Chant + Tormod's Cryptkeeper + Capture of Jingzhou

Deadbridge Chant

Tormod's Cryptkeeper

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.

By leveraging Tormod's Cryptkeeper to cleanly exile your graveyard after casting a spell, you ensure that Deadbridge Chant has only one possible target to select during your upkeep. When Deadbridge Chant triggers, it will always randomly select and return Capture of Jingzhou from your newly refilled graveyard directly to your hand. This sets up a recursive engine where you can replay Capture of Jingzhou turn after turn, locking down the game with infinite extra turns as long as no stray cards disrupt your graveyard.
