Golgari Thug + Goblin Bombardment + Dross Harvester + Gwenom, Remorseless

Golgari Thug

Goblin Bombardment

Dross Harvester

Gwenom, Remorseless

How it works

1. Activate Goblin Bombardment by sacrificing Golgari Thug.
2. When Golgari Thug dies, it and Dross Harvester trigger.
3. Resolve the Golgari Thug trigger, putting it from your graveyard onto the top of your library.
4. Resolve the Dross Harvester trigger, causing you to gain 2 life.
5. Resolve the Goblin Bombardment ability.
6. Cast Golgari Thug from the top of your library by paying 2 life.
7. Repeat.

This clever loop hinges on recurring Golgari Thug endlessly by sacrificing it to Goblin Bombardment, which triggers both the Thug's own replacement-style grave-sorting and Dross Harvester's life-buffing static observation. Because Gwenom, Remorseless is on the battlefield granting the ability to play cards from the top of your library while bypassing their mana costs with life payments, you can immediately recast the Thug right back onto the battlefield. Dross Harvester helps cushion the life toll exacted by Gwenom, Remorseless, letting you endlessly churn your sacrificial engine to burn out the table.
