This clever loop turns Putrid Goblin and Vizier of Remedies into an engine for infinite triggers by negating the drawback of persist entirely, as Vizier of Remedies reduces the incoming -1/-1 counter to zero and allows Putrid Goblin to keep returning endlessly. Meanwhile, Phantom Train acts as the essential sacrifice outlet that keeps the loop running while feeding itself the fruits of the cycle, stacking infinite +1/+1 counters onto its chassis. Together, these pieces turn the graveyard and the battlefield into a perpetual motion machine that generates infinite deaths, enters-the-battlefield events, and leaves-the-battlefield triggers at will.
