Scouring Swarm + Drownyard Temple + Thermopod + Sylvan Safekeeper

Scouring Swarm

Drownyard Temple

Thermopod

Sylvan Safekeeper

How it works

1. Activate Sylvan Safekeeper by sacrificing Drownyard Temple.
2. Each Scouring Swarm you control triggers, creating a tapped token copy of itself.
3. Resolve the Sylvan Safekeeper 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 loop turns your own land into a recursive engine by using Sylvan Safekeeper to feed Drownyard Temple directly into the graveyard. Once your graveyard holds at least seven lands, Scouring Swarm scales up its trigger to multiply itself into token copies rather than mere insects. Thermopod then acts as the red mana refinery, letting you sacrifice excess swarm tokens to fund Drownyard Temple's return to the battlefield and restart the cycle.
