Scouring Swarm + Drownyard Temple + Thermopod + Troubled Healer

Scouring Swarm

Drownyard Temple

Thermopod

Troubled Healer

How it works

1. Activate Troubled Healer by sacrificing Drownyard Temple.
2. Each Scouring Swarm you control triggers, creating a tapped token copy of itself.
3. Resolve the Troubled Healer ability.
4. If you control four or more Scouring Swarms, activate Thermopod by sacrificing a Scouring Swarm, adding .
5. Repeat step 4 until you control three Scouring Swarms or until you have 3 available, whichever comes first.
6. Activate Drownyard Temple by paying 3, returning it from your graveyard to the battlefield.
7. Repeat.

This clever feedback loop relies on Troubled Healer to continuously sacrifice Drownyard Temple as its cost, seeding your graveyard with the land while triggering a cascade of copies from Scouring Swarm once you cross the threshold of seven land cards in your graveyard. Thermopod acts as your sacrifice outlet and red mana engine, converting the extra Swarm tokens into the fuel needed to pay the activation cost of Drownyard Temple and bring it right back to the battlefield. By cycling the land in and out of the grave, you feed an ever-expanding swarm of hasty insects that can be endlessly traded for infinite red mana and cascading triggers.
