Disa the Restless + Enduring Renewal + Circling Vultures + Ashes of the Fallen + Phantom Train

Disa the Restless

Enduring Renewal

Circling Vultures

Ashes of the Fallen

Phantom Train

How it works

1. Discard Circling Vultures from your hand using its static ability.
2. Because Circling Vultures is a Lhurgoyf due to Ashes of the Fallen, Disa the Restless's first ability triggers, putting Circling Vultures from your graveyard onto the battlefield.
3. Activate Phantom Train by sacrificing Circling Vultures.
4. When Circling Vultures dies, Enduring Renewal triggers, returning Circling Vultures from your graveyard to the battlefield.
5. Resolve the Phantom Train ability
6. Repeat.

This looping engine turns a neat trick of types and triggers into a self-sustaining machine. With Ashes of the Fallen set to Lhurgoyf, discarded creatures like Circling Vultures are instantly caught by Disa the Restless and cheated directly onto the battlefield. From there, you feed Circling Vultures into Phantom Train's activation cost, triggering Enduring Renewal to seamlessly bounce the bird right back to your hand so you can pitch it all over again.
