Teysa, Orzhov Scion + Darkest Hour + Phantom Train

Teysa, Orzhov Scion

Darkest Hour

Phantom Train

How it works

1. Activate Phantom Train by sacrificing another creature.
2. When the creature dies, Teysa triggers, creating a 1/1 Spirit creature token that is black due to Darkest Hour.
3. Resolve the Phantom Train ability.
4. Repeat.

This clever loop turns Phantom Train into an endless sacrifice engine by leaning on a clever color-pie interaction: Darkest Hour paints every creature black, meaning the Spirit token created by Teysa, Orzhov Scion is immediately a black creature. Because of this, every time you feed a creature to Phantom Train's activation cost, Teysa replaces it by spawning a fresh 1/1 Spirit to take its place. This creates an uninterrupted chain of sacrifices, leaving you with infinite death triggers and leaving your opponents' boards at your absolute mercy.
