Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Melira's Keepers + Umbral Collar Zealot

Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Melira's Keepers

Umbral Collar Zealot

How it works

1. Activate Umbral Collar Zealot by sacrificing Melira's Keepers
2. When Melira's Keepers dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to its static effect.
3. Resolve the Umbral Collar Zealot ability.
4. Repeat.

This elegant loop turns Umbral Collar Zealot into a bottomless pit for sacrifice, but the true brilliance lies in the support system holding it together. While Melira's Keepers would normally succumb to the -1/-1 counters generated by its own persist ability, its static clause completely shuts that drawback down, allowing it to return to the battlefield fresh every single time it dies. Meanwhile, Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight serves a double duty: its front face helps weave your creatures together, while its transformed state grants the persist ability that makes this infinite engine possible.
