Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Scholar of New Horizons + Yahenni, Undying Partisan

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

Scholar of New Horizons

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Scholar of New Horizons.
2. When Scholar of New Horizons 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.
