Saffi Eriksdotter + Jackdaw Savior + Phantom Train

Saffi Eriksdotter

Jackdaw Savior

Phantom Train

How it works

1. Activate Saffi by sacrificing it, targeting Jackdaw Savior.
2. Activate Phantom Train by sacrificing Jackdaw Savior.
3. When Jackdaw Savior dies, it and Saffi trigger.
4. Resolve the Jackdaw Savior trigger, returning Saffi from your graveyard to the battlefield.
5. Resolve the Saffi trigger, returning Jackdaw Savior from your graveyard to the battlefield.
6. Resolve the Phantom Train ability.
7. Repeat.

This clever loop relies on a recursive partnership between Saffi Eriksdotter and Jackdaw Savior, where each death continuously resurrects the other. You kick off the engine by sacrificing Saffi to target Jackdaw Savior, then use Phantom Train's sacrifice outlet to bin Jackdaw Savior and fuel its own +1/+1 counter growth. Because Jackdaw Savior has a lesser mana value than Saffi, its death trigger pulls Saffi right back onto the battlefield, while Saffi's delayed trigger simultaneously returns Jackdaw Savior. With Phantom Train happily munching away at the resulting sacrifices, this cycle generates infinite creature leaves-the-battlefield, enters-the-battlefield, death triggers, and endlessly stacks +1/+1 counters on your Vehicle.
