Melira, Sylvok Outcast + Umbral Collar Zealot + River Kelpie

Melira, Sylvok Outcast

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 Melira.
3. When River Kelpie enters, it triggers, causing you to draw a card
4. Resolve the Umbral Collar Zealot ability.
5. Repeat.

This loop turns Umbral Collar Zealot into a relentless sacrifice engine for River Kelpie, fueling a continuous cycle of death and rebirth. Melira, Sylvok Outcast is the linchpin that stops persist from permanently disabling the Kelpie, negating the -1/-1 counters so the creature can return to the battlefield fresh every single time. As River Kelpie repeatedly re-enters from the graveyard, its triggered ability fires over and over, letting you draw your entire deck.
