This elegant engine converts the cycle of life and death into pure, unadulterated devastation by leveraging Blasting Station as both the sacrificial altar and the recurring artillery piece. Every time Tenacious Dead meets its end, Pitiless Plunderer quietly hoards the resulting wealth while Rat King, Pale Piper steps in to generate a fresh sacrificial body whenever a nontoken leaves the battlefield. That newly created token lets Blasting Station untap itself to continue the barrage, while the Treasures fueled by Pitiless Plunderer provide the exact {1}{B} needed to resurrect Tenacious Dead from the graveyard and start the loop anew.
