Deadbridge Chant + Tormod's Cryptkeeper + Walk the Aeons

Deadbridge Chant

Tormod's Cryptkeeper

Walk the Aeons

How it works

1. Activate Tormod's Crpyt by tapping and sacrificing it, exiling your graveyard.
2. Cast Walk the Aeons by paying 4, 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 Walk the Aeons 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.
