Brotherhood Outcast + Unholy Indenture + Phantom Train

Brotherhood Outcast

Unholy Indenture

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Brotherhood Outcast.
2. When Brotherhood Outcast dies, Unholy Indenture triggers, returning Brotherhood Outcast from your graveyard to the battlefield.
3. When Brotherhood Outcast enters the battlefield, it triggers, returning Unholy Indenture from your graveyard to the battlefield attached to Brotherhood Outcast.
4. Resolve the Phantom Train ability.
5. Repeat.

This clever loop relies on an infinite recursive dance of resurrection and reattachment, completely fueled by the sacrifices demanded by Phantom Train. When you sacrifice Brotherhood Outcast to the Train, Unholy Indenture steps in upon its death to instantly bring the Outcast right back to the battlefield. That new entry triggers the Outcast's own ability, allowing it to fish Unholy Indenture back out of the graveyard and re-equip itself, neatly resetting the entire loop so Phantom Train can devour it all over again.
