Eloise, Nephalia Sleuth + Cauldron Familiar + Peregrin Took + Phantom Train

Eloise, Nephalia Sleuth

Cauldron Familiar

Peregrin Took

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Cauldron Familiar.
2. When Cauldron Familiar dies, Eloise's first ability triggers, creating a Clue and Food token.
3. Resolve the Phantom Train ability
4. Activate Cauldron Familiar by sacrificing a Food.
5. Eloise's second ability triggers, causing you to surveil 1.
6. Resolve the Cauldron Familiar ability, returning it from your graveyard to the battlefield.
7. When Cauldron Familiar enters the battlefield, it triggers, causing each opponent to lose 1 life and you to gain 1 life.
8. Repeat.

This loop transforms a humble cat into an unstoppable engine of life-drain and deck manipulation. Phantom Train acts as the sacrifice outlet that kicks things off by sending Cauldron Familiar to the graveyard, which triggers Eloise, Nephalia Sleuth to investigate. Thanks to Peregrin Took's replacement effect, that single Clue generation is upgraded to include an extra Food token, providing the exact resource needed to bring Cauldron Familiar right back to the battlefield. Every single iteration drains your opponents while Eloise’s built-in surveil smooths out your draws, letting you grow Phantom Train infinitely with a mountain of recycled tokens.
