Anticausal Vestige + Paleoloth + Body Double + Phantom Train

Anticausal Vestige

Paleoloth

Body Double

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Anticausal Vestige.
2. When Anticausal Vestige dies, it triggers, causing you to draw a card and put Body Double from your hand onto the battlefield tapped. Choose to have Body Double enter as a copy of Anticausal Vestige.
3. When Body Double enters, Paleoloth triggers, returning Anticausal Vestige from your graveyard to your hand.
4. Resolve the Phantom Train ability.
5. Activate Phantom Train by sacrificing Body Double.
6. When Body Double dies, it triggers, causing you to draw a card and put Anticausal Vestige from your hand onto the battlefield tapped.
7. When Anticausal Vestige enters, Paleoloth triggers, returning Body Double from your graveyard to your hand.
8. Resolve the Phantom Train ability.
9. Repeat.

This clever loop sets up an endless cycle of sacrifice and rebirth by using Phantom Train to repeatedly munch on your own creatures. Whenever Anticausal Vestige and Body Double take turns hitting the graveyard, Anticausal Vestige's leaves-the-battlefield trigger pulls the other straight from your hand onto the battlefield. Meanwhile, Paleoloth watches from the sidelines, using its power-triggered ability to continuously fish the fallen copy right back to your hand so the cycle can start anew.
