Golgari Thug + Healer of the Pride + Bolas's Citadel + Phantom Train

Golgari Thug

Healer of the Pride

Bolas's Citadel

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Golgari Thug.
2. When Golgari Thug dies, it triggers, putting it from your graveyard onto the top of your library.
3. Resolve the Phantom Train ability.
4. Cast Golgari Thug from the top of your library by paying 2 life.
5. When Golgari Thug enters, Healer of the Pride triggers, causing you to gain 2 life.
6. Repeat.

This clever loop lets you recast Golgari Thug over and over straight from the top of your library, fueled entirely by Bolas's Citadel allowing you to pay life instead of mana. Phantom Train provides the necessary sacrifice outlet to send the Thug back to the graveyard, triggering its own ability to immediately return itself right back to the top of your library. Meanwhile, Healer of the Pride effortlessly offsets the life cost paid into Bolas's Citadel by gaining you life with every single creature entry, turning a self-sustaining sacrifice engine into an endless fountain of triggers.
