Olivia, Mobilized for War + Liliana, Dreadhorde General + Phantom Train

Olivia, Mobilized for War

Liliana, Dreadhorde General

Phantom Train

How it works

1. Activate Phantom Train by sacrificing the persist creature.
2. When the persist creature dies, it and Liliana, Dreadhorde General trigger.
3. Resolve the Liliana, Dreadhorde General 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 ingenious loop transforms a persist creature into an endless engine of sacrifice and rebirth by using Phantom Train as a repeatable sacrifice outlet that simultaneously grows itself into a creature. Whenever your persist creature dies, Liliana, Dreadhorde General takes notice to keep your hand full of options while fueling your death triggers. Meanwhile, every time that creature stumbles back onto the battlefield, Olivia, Mobilized for War steps in to discard a card and slap a +1/+1 counter on it—which immediately neutralizes its incoming -1/-1 counter and ensures the creature is ready to be sacrificed to Phantom Train all over again.
