Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Shilgengar, Sire of Famine + Selfless Police Captain

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

Shilgengar, Sire of Famine

Selfless Police Captain

How it works

1. Activate Shilgengar by sacrificing Selfless Police Captain.
2. When Selfless Police Captain dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to its replacement effect.
3. Resolve the Shilgengar ability.
4. Repeat.

This elegant loop is orchestrated by Shilgengar, Sire of Famine, whose sacrifice outlet transforms every cycle into a bounty of Blood tokens. The engine is fueled by Isilu, Carrier of Twilight—the night-facing side of Eirdu, Carrier of Dawn—which bestows persist onto your other nontoken creatures so they can cheat death and return with a -1/-1 counter. Selfless Police Captain steps into this loop perfectly, entering with a +1/+1 counter that immediately cancels out Shilgengar's incoming -1/-1 counter when it returns. By constantly dying, triggering its own counter-buff on leaves-the-battlefield, and coming right back via persist, the Police Captain keeps the sacrifice grinder turning indefinitely without ever succumbing to its counters.
