Deadbridge Chant + Tormod's Cryptkeeper + Time Walk

Deadbridge Chant

Tormod's Cryptkeeper

Time Walk

How it works

1. Activate Tormod's Cryptkeeper by tapping and sacrificing it, exiling your graveyard.
2. Cast Time Walk by paying 1, 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 Walk 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 Vintage-legal engine leverages Deadbridge Chant to recur and cast Time Walk on every single extra turn you take, securing infinite turns as long as your graveyard remains pristine. The crucial linchpin making this deterministic is Tormod's Cryptkeeper, whose activated ability lets you surgically wipe away any stray cards from your graveyard. By ensuring that Time Walk is the *only* card dwelling in your graveyard when your upkeep begins, the random selection of Deadbridge Chant becomes a guaranteed 100% hit every time.
