This clever loop relies on a recursive exchange between Ozox, the Clattering King and its skeletal counterpart, Jumblebones, using Thermopod to turn their deaths into red mana and Pitiless Plunderer to generate Treasures that help pay for casting costs. Every time Ozox is sacrificed to Thermopod, it leaves behind Jumblebones, whose own subsequent sacrifice to the same Thermopod triggers a return effect that pulls Ozox right back to your hand. Meanwhile, Pitiless Plunderer quietly watches the cycle and rewards every single death with a steady stream of artifacts, letting you endlessly recast Ozox and fuel an infinite storm or sacrifice engine.
