Judith, the Scourge Diva + Skittering Precursor + Sword of the Meek + Umbral Collar Zealot

Judith, the Scourge Diva

Skittering Precursor

Sword of the Meek

Umbral Collar Zealot

How it works

1. Activate Umbral Collar Zealot by sacrificing Sword of the Meek.
2. Skittering Precursor triggers, creating a 0/1 Eldrazi Spawn creature token.
3. When the Eldrazi Spawn enters the battlefield as a 1/1 due to Judith, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Eldrazi Spawn.
4. Resolve the Umbral Collar Zealot ability
5. Repeat.

This clever loop turns Umbral Collar Zealot's sacrifice outlet into an engine for infinite resources by exploiting the interaction between Sword of the Meek and Judith, the Scourge Diva. Because Judith grants a static +1/+0 buff to your other creatures, the 0/1 Eldrazi Spawn token created by Skittering Precursor enters the battlefield as a 1/1, which immediately satisfies the trigger condition to bring Sword of the Meek back from the graveyard and attach it. You can then sacrifice the sword right back to Umbral Collar Zealot to keep the cycle going, generating endless mana from the Spawn tokens while clearing away your library with infinite surveil triggers and pinging down any target thanks to Judith's death trigger.
