Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Weaponcraft Enthusiast + Yahenni, Undying Partisan

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

Weaponcraft Enthusiast

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Weaponcraft Enthusiast.
2. When Weaponcraft Enthusiast dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Weaponcraft Enthusiast enters, its fabricate ability triggers, putting a +1/+1 counter on it.
4. Resolve the Yahenni ability.
5. Repeat.

This clever loop turns Isilu, Carrier of Twilight's granted persist ability into an engine of continuous rebirth by relying on the math of +1/+1 and -1/+1 counters. When you sacrifice Weaponcraft Enthusiast to Yahenni, Undying Partisan's activation, persist returns it with a -1/-1 counter, but its fabricate 2 ability immediately counters this drawback by placing a +1/+1 counter on it—which state-based actions then combine and annihilate, leaving the Enthusiast completely clean and ready to die all over again. While Eirdu, Carrier of Dawn is waiting on the reverse side to help cast creature spells with convoke, it is Isilu's passive bestowal of persist that truly makes this infinite sacrifice and death loop possible.
