Yawgmoth, Thran Physician + Nest of Scarabs + Vengeful Bloodwitch

Yawgmoth, Thran Physician

Nest of Scarabs

Vengeful Bloodwitch

How it works

1. Activate Yawgmoth by paying 1 life and sacrificing another creature.
2. When the creature dies, Vengeful Bloodwitch 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 clever loop transforms Yawgmoth, Thran Physician's sacrifice outlet into a self-sustaining engine by utilizing Nest of Scarabs to replace every sacrificed creature with a fresh Insect token. As these bodies cycle through the graveyard, Vengeful Bloodwitch converts every single death and subsequent token generation into an unescapable drain on your opponents' life totals. Because Yawgmoth, Thran Physician lets you draw cards and distribute -1/-1 counters along the way, you can easily dig through your entire deck to fuel the loop while systematically clearing away any opposing blockers.
