Yawgmoth, Thran Physician + Nest of Scarabs + Susurian Voidborn

Yawgmoth, Thran Physician

Nest of Scarabs

Susurian Voidborn

How it works

1. Activate Yawgmoth by paying 1 life and sacrificing another creature.
2. When the creature dies, Susurian Voidborn triggers, causing you to gain 1 life and target opponent to lose 1 life.
3. Resolve the Yawgmoth ability, putting a -1/-1 counter on any other creature and causing you to draw a card.
4. If the creature who had the counter placed has 0 toughness, it dies as a state-based action.
5. Nest of Scarabs triggers, creating a 1/1 Insect creature token.
6. Repeat until your opponents do not control any more creatures, or until you draw your library.
7. If you have cards remaining in your library, you may repeat this combo any time a creature enters the battlefield under an opponent's control.

This elegant loop turns Yawgmoth, Thran Physician into a relentless card-drawing and removal engine by feeding it a self-sustaining cycle of sacrifices and insect swarms. Whenever you sacrifice a creature to Yawgmoth's activation, Nest of Scarabs instantly replaces it by spawning a 1/1 black Insect token to feed back into the grinder. Meanwhile, Susurian Voidborn quietly capitalizes on every single casualty by draining your opponent's life total while padding your own, easily neutralizing the life cost of Yawgmoth's ability until you draw your entire library or clear the board.
