Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Carrion Feeder + Cayth, Famed Mechanist

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

Carrion Feeder

Cayth, Famed Mechanist

How it works

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

This ingenious loop transforms the daytime face of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight into its dark half to grant your team persist, turning the graveyard into a revolving door for your other creatures. With that passive protection active, you can feed Cayth, Famed Mechanist to Carrion Feeder, letting the mechanist's own fabricate ability—or the team-wide bonus granted by Cayth—instantly cancel out the returning -1/-1 counter with a +1/+1 counter. Because Carrion Feeder happily accepts repeated sacrifices while growing larger with every iteration, you generate boundless sacrificial momentum and trigger counts without ever running out of fodder.
