Olivia, Mobilized for War + Phantom Train + Tresserhorn's Lord, Returned

Olivia, Mobilized for War

Phantom Train

Tresserhorn's Lord, Returned

How it works

1. Activate Phantom Train by sacrificing the persist creature.
2. When the persist creature dies, it and Tresserhorn's Lord trigger.
3. Resolve the Tresserhorn's Lord trigger, causing you to draw a card.
4. Resolve the persist creature's trigger, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
5. When the persist creature enters the battlefield, Olivia triggers, putting a +1/+1 counter on the persist creature and causing you to discard a card.
6. Resolve the Phantom Train ability.
7. Repeat.

This engine turns a persistent loop of sacrifices into an unstoppable cascade of value by relying on Olivia, Mobilized for War to continuously buff your returning creature and stoke your hand with her looting trigger. As your persist creature hits the graveyard, Tresserhorn's Lord, Returned steps in to convert every single sacrifice into a fresh card drawn, turning the death toll straight into fuel. Meanwhile, Phantom Train acts as the mechanical engine room, providing the repeatable sacrifice outlet needed to keep the cycle going while growing itself into a massive threat.
