Sun Titan + Angelic Renewal + Phantom Train

Sun Titan

Angelic Renewal

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Sun Titan.
2. When Sun Titan dies, Angelic Renewal triggers, causing you to sacrifice Angelic Renewal and return Sun Titan from your graveyard to the battlefield.
3. When Sun Titan enters, it triggers, returning Angelic Renewal from your graveyard to the battlefield.
4. Resolve the Phantom Train ability.
5. Repeat.

This clever loop turns the cycle of life and death into a perpetual motion machine by leveraging Angelic Renewal to catch Sun Titan every time it hits the graveyard. Since Sun Titan's entry trigger conveniently returns Angelic Renewal right back to the battlefield, you have all the pieces needed to keep the recursion going indefinitely. Meanwhile, Phantom Train acts as the willing executioner for your engine, using its sacrifice ability to continuously pump itself with +1/+1 counters while feeding the loop.
