Lurrus of the Dream-Den + Kaya's Ghostform + Pitiless Plunderer + Phantom Train

Lurrus of the Dream-Den

Kaya's Ghostform

Pitiless Plunderer

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Lurrus of the Dream-Den.
2. When Lurrus of the Dream-Den dies, Kaya's Ghostform and Pitiless Plunderer trigger.
3. Resolve the Kaya's Ghostform trigger, returning Lurrus of the Dream-Den from your graveyard to the battlefield.
4. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
5. Resolve the Phantom Train ability
6. Activate the Treasure by tapping and sacrificing it, adding .
7. Cast Kaya's Ghostform from your graveyard by paying , attaching it to Lurrus of the Dream-Den.
8. Repeat.

This clever loop relies on Phantom Train to repeatedly sacrifice Lurrus of the Dream-Den, which is kept safe by Kaya's Ghostform returning it straight to the battlefield each time it dies. Meanwhile, Pitiless Plunderer quietly watches the carnage and converts every sacrifice into a fresh Treasure token. You can then use that generated mana to recast Kaya's Ghostform right out of your graveyard, utilizing the companion's own recursion ability to keep the cycle spinning forever.
