This elegant loop turns Grazing Kelpie into a perpetual sacrifice engine by exploiting its native persist ability. Whenever Grazing Kelpie dies and tries to return with a -1/-1 counter, Vizier of Remedies steps in with its replacement effect to ensure no counters are placed at all, leaving the creature completely clean and ready to persist again. You can feed this endlessly to Viscera Seer to churn through your deck with infinite scry triggers while generating boundless enter-the-battlefield, leave-the-battlefield, and death events.
