Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Yahenni, Undying Partisan + Hulk, Strongest There Is

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

Yahenni, Undying Partisan

Hulk, Strongest There Is

How it works

1. Activate Yahenni by sacrificing Hulk.
2. When Hulk 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 Yahenni ability.
4. Repeat.

This clever loop hinges on the front and back faces of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight working in tandem with the rest of the board to establish an infinite sacrifice engine. While Eirdu's front face gives your creature spells convoke, it is its back face, Isilu, Carrier of Twilight, that grants each other nontoken creature you control persist, allowing fallen allies to return with a -1/-1 counter. You can feed this recursion directly into Yahenni, Undying Partisan, whose ability lets you sacrifice another creature to temporarily grant it indestructible while growing larger from opponent deaths. By repeatedly sacrificing Hulk, Strongest There Is to Yahenni, Hulk's newly gained persist ability immediately triggers to return it to the battlefield, endlessly generating death triggers, sacrifice triggers, and creature entries.
