Deadbridge Chant + Tormod's Crypt + Time Warp

Deadbridge Chant

Tormod's Crypt

Time Warp

How it works

1. Activate Tormod's Crpyt by tapping and sacrificing it, exiling your graveyard.
2. Cast Time Warp 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 Time Warp 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.
