This potent engine turns the graveyard into a revolving door by leveraging Luminous Broodmoth to constantly resurrect your grounded threats. While Goblin Bombardment provides a reliable sacrifice outlet to cash in creatures for direct damage, Pitiless Plunderer fuels the loop by generating a steady stream of Treasure tokens off every death. Finally, Slimefoot and Squee acts as both a self-recurring focal point that spawns Saproling tokens upon entering the battlefield and an alternative recursion engine to pull everything else right back when the Broodmoth eventually needs to be brought home.
