This vicious loop transforms a hefty mana value into an endless engine of dark resurrection by leaning on the persistent synergy between Illuminor Szeras and Nim Deathmantle. When you feed a creature with a mana value of four or greater to Illuminor Szeras's sacrifice ability, you generate the exact amount of black mana needed to immediately fund the return of that same creature via Nim Deathmantle's trigger. Meanwhile, Dross Scorpion acts as the mechanical heart of the machine, utilizing its triggered ability to untap Illuminor Szeras every time an artifact creature dies so the ritual can begin anew.
