Golgari Thug + Viscera Seer + Dross Harvester + Bolas's Citadel

Golgari Thug

Viscera Seer

Dross Harvester

Bolas's Citadel

How it works

1. Activate Viscera Seer 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 Viscera Seer ability.
6. Cast Golgari Thug from the top of your library by paying 2 life.
7. Repeat.

This loop sets up a self-sustaining engine built right off the top of your library. Viscera Seer provides a zero-mana outlet to sacrifice Golgari Thug, whose own death trigger immediately returns itself to the top of your library instead of letting it stay in the graveyard. Meanwhile, Bolas's Citadel lets you bypass mana costs to recast that same Golgari Thug directly from the library by paying just 2 life. Dross Harvester effortlessly offsets that life payment by generating a net-neutral life total each time a creature dies, turning this closed-loop sequence into an engine for infinite sacrifices, death triggers, and storm count.
