Whisper, Blood Liturgist + Necrotic Ooze + Black Carriage + Underworld Hermit

Whisper, Blood Liturgist

Necrotic Ooze

Black Carriage

Underworld Hermit

How it works

1. During your upkeep, activate Necrotic Ooze using Whisper's ability by tapping it and sacrificing two other creatures, returning Underworld Hermit from your graveyard to the battlefield.
2. When Underworld Hermit enters the battlefield, it triggers, creating at least four 1/1 Squirrel creature tokens.
3. Activate Necrotic Ooze using Black Carriage's ability by sacrificing Underworld Hermit, untapping Necrotic Ooze.
4. Repeat.

This clever loop transforms Necrotic Ooze into a one-stop engine by leveraging the activated abilities of creatures resting in the graveyard. Once Whisper, Blood Liturgist's sacrifice ability is channeled through the Ooze, you can pull Underworld Hermit straight from your graveyard to the battlefield, where its devotion-based entry naturally floods the board with Squirrel tokens. Black Carriage's graveyard-accessible ability then steps in to untap the Ooze at instant speed during your upkeep by feeding one of those newly minted creatures back to the sacrifice grinder. Because Black Carriage itself sits quietly in the graveyard providing the vital untap lever—while its innate trample and untap-restriction text safely fade into the background—the loop can endlessly churn through sacrifices, entry triggers, and graveyard returns without ever running out of fuel.
