Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Grim Poppet + Krark-Clan Ironworks

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

Grim Poppet

Krark-Clan Ironworks

How it works

1. If Grim Poppet has any -1/-1 counters on it, activate it by removing a -1/-1 counter from it.
2. Repeat step 1 as necessary until Grim Poppet has no -1/-1 counters on it.
3. Activate Krark-Clan Ironworks by sacrificing Grim Poppet.
4. When Grim Poppet dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
5. Repeat.
6. Resolve all Grim Poppet abilities, putting infinite -1/-1 counters on any number of creatures.

This delightfully morbid loop transforms the nocturnal side of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight into an engine of endless sacrifice by granting your nontoken creatures persist, which allows Grim Poppet to return from the graveyard with a -1/-1 counter whenever it dies. Before feeding it to Krark-Clan Ironworks for a steady stream of colorless mana, you can strip away Grim Poppet's initial counters using its own activated ability to permanently wither down opposing boards. The daytime side, Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight, even weaves convoke into your creature spells to help you set the board while you orchestrate this recursive doom.
