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

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

Thermopod

Cayth, Famed Mechanist

How it works

1. Activate Thermopod 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. Repeat.

This fiery loop turns a quiet mechanical cycle into an infinite engine, fueled by Isilu, Carrier of Twilight's passive grant of persist to your other nontoken creatures, which lets Cayth, Famed Mechanist slip right back from the graveyard onto the battlefield with a -1/-1 counter. Thermopod provides the crucial sacrifice outlet that converts Cayth into red mana while instantly triggering that very same persist loop. Whenever Cayth returns, its built-in fabricate ability triggers anew, placing a +1/+1 counter that neatly cancels out the -1/-1 counter to ensure the cycle can repeat indefinitely. Meanwhile, Eirdu, Carrier of Dawn waits in the wings with its creature-spell convoke ability, ready to harness the vast magical potential of your setup.
