Brotherhood Outcast + Minion's Return + Phantom Train

Brotherhood Outcast

Minion's Return

Phantom Train

How it works

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

This clever little loop uses Phantom Train as an engine to repeatedly sacrifice Brotherhood Outcast, feeding your death and sacrifice triggers to infinity while stacking up endless +1/+1 counters on the Vehicle. The magic holding this whole cycle together is Minion's Return, whose triggered ability intercepts Brotherhood Outcast the moment it hits the graveyard and sneaks it right back onto the battlefield. From there, Brotherhood Outcast's own enters-the-battlefield ability immediately triggers to fish Minion's Return back out of the graveyard and reattach it, resetting the entire process for another iteration.
