Archelos, Lagoon Mystic + Lotus Cobra + Squandered Resources + Drownyard Temple

Archelos, Lagoon Mystic

Lotus Cobra

Squandered Resources

Drownyard Temple

How it works

1. Activate Drownyard Temple's first ability by tapping it, adding C.
2. Activate Squandered Resources by sacrificing Drownyard Temple, adding C.
3. Activate Drownyard Temple's second ability by paying 3, returning it from your graveyard to the battlefield untapped due to Archelos.
4. When Drownyard Temple enters the battlefield, Lotus Cobra triggers, adding 1.
5. Repeat.

This clever loop turns Drownyard Temple's graveyard-recursion ability into a self-sustaining engine by carefully manipulating land entry states. While Squandered Resources turns the Temple into mana through sacrifice, Archelos, Lagoon Mystic steps in as the linchpin of the combo: as long as Archelos is untapped, it overrides the Temple's native return-tapped clause, ensuring Drownyard Temple enters the battlefield untapped. That fresh entry triggers Lotus Cobra's landfall ability to generate the extra mana needed to fund the cycle, leaving you with an endless loop of sacrifices, returns, and infinite landfall triggers.
