Mortuary + Skirk Prospector + Bolas's Citadel + Blood Artist

Mortuary

Skirk Prospector

Bolas's Citadel

Blood Artist

How it works

1. Activate Skirk Prospector by sacrificing it.
2. When Skirk Prospector dies, Mortuary and Blood Artist trigger.
3. Resolve the Mortuary trigger, putting Skirk Prospector from your graveyard onto the top of your library.
4. Resolve the Blood Artist trigger, causing you to gain 1 life and target opponent to lose 1 life.
5. Cast Skirk Prospector from the top of your library by paying 1 life.
6. Repeat.

This vicious loop transforms a simple Goblin into an engine of endless attrition by leaning on Bolas's Citadel to bypass mana costs with life instead. As Skirk Prospector feeds its own sacrifice ability for red mana, Mortuary catches it on the way to the graveyard and immediately tucks it back onto the top of your library for the Citadel to play again. Meanwhile, Blood Artist watches the endless procession of sacrifices to drain your opponents dry while simultaneously padding your life total to safely fuel the Citadel's life-payment cost.
