Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Spawning Pit + Arcbound Lancer

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

Spawning Pit

Arcbound Lancer

How it works

1. Activate Spawning Pit by sacrificing Arcbound Lancer.
2. When Arcbound Lancer dies, its modular ability and persist ability trigger.
3. Resolve the modular trigger, putting Arcbound Lancer's +1/+1 counters on another artifact creature.
4. Resolve the persist trigger, returning Arcbound Lancer from your graveyard to the battlefield. It will not have a -1/-1 counter on it due to its modular ability.
5. Resolve the Spawning Pit ability.
6. Repeat.

This elegant loop centers on the recursive resurrection granted by the back face of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight, which bestows persist upon your other nontoken creatures, such as Arcbound Lancer. When you sacrifice Arcbound Lancer to Spawning Pit, its modular ability places four +1/+1 counters onto another artifact creature while its persist ability returns it to the battlefield; the newly added counters instantly cancel out any -1/-1 counter it would have received, keeping the cycle completely fresh. Meanwhile, its front face (Eirdu, Carrier of Dawn) helps you cast creature spells by giving them convoke, and Spawning Pit steadily accumulates charge counters to fuel your artifact token production alongside all those death and ETB triggers.
