Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Grim Poppet + Blasting Station

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

Grim Poppet

Blasting Station

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 Blasting Station by tapping it and 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. When Grim Poppet enters, Blasting Station triggers, untapping Blasting Station.
6. Resolve the Blasting Station ability from step 3.
7. Repeat.
8. Resolve all Grim Poppet abilities, putting infinite -1/-1 counters on any number of creatures.

This clever loop turns Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight's backside into a self-sustaining engine of attrition, granting your other nontoken creatures persist so they refuse to stay in the graveyard. By feeding Grim Poppet into Blasting Station, you leverage the Poppet's own ability to strip away its -1/-1 counters or sacrifice it directly, triggering the Station's untap ability every time it returns. Each cycle loops Grim Poppet cleanly back to the battlefield to be sacrificed anew, letting you ping opponents endlessly while systematically neutralizing any creature that dares to enter under their control.
