Vizier of Remedies + Umbral Collar Zealot + River Kelpie

Vizier of Remedies

Umbral Collar Zealot

River Kelpie

How it works

1. Activate Umbral Collar Zealot by sacrificing River Kelpie.
2. When River Kelpie dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Vizier of Remedies.
3. When River Kelpie enters, its first ability triggers, causing you to draw a card.
4. Resolve the Umbral Collar Zealot ability.
5. Repeat.

This elegant loop relies on Umbral Collar Zealot acting as a perpetual sacrifice outlet that feeds right back into your engine. Whenever you feed River Kelpie to the Zealot, its persist ability triggers to bring it right back, but Vizier of Remedies steps in to intercept the incoming -1/-1 counter entirely. Because River Kelpie enters the battlefield cleanly from the graveyard, its own ability triggers to draw you a card, letting you churn through your entire library while generating endless death and entering-the-battlefield triggers.
