Scouring Swarm + Drownyard Temple + Phyrexian Altar + Squandered Resources

Scouring Swarm

Drownyard Temple

Phyrexian Altar

Squandered Resources

How it works

1. Activate Squandered Resources by sacrificing Drownyard Temple, adding C.
2. Each Scouring Swarm you control triggers, creating a tapped token copy of itself.
3. If you control three or more Scouring Swarms, activate Phyrexian Altar by sacrificing a Scouring Swarm, adding 1.
4. Repeat step 4 until you control two Scouring Swarms or until you have 3 available, whichever comes first.
5. Activate Drownyard Temple by paying 3, returning it from your graveyard to the battlefield.
6. Repeat.

This clever loop turns the cycle of land sacrifice and rebirth into an engine of exponential growth, fueled entirely by the clever synergy between your mana outlets and recursive threats. By leveraging Squandered Resources, you bin Drownyard Temple for mana while simultaneously feeding Scouring Swarm's threshold requirement once your graveyard holds seven or more land cards. As your Swarm army multiplies, Phyrexian Altar steps in to convert those disposable token copies into the exact colored mana needed to pay Drownyard Temple's resurrection cost. The result is a self-sustaining loop that continuously floods the board with tapped copies of Scouring Swarm while generating an infinite surplus of mana and triggers.
