Havi, the All-Father + Sakashima the Impostor + Yahenni, Undying Partisan

Havi, the All-Father

Sakashima the Impostor

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Sakashima the Impostor.
2. When Sakashima the Impostor dies, it and Havi trigger.
3. Resolve the Havi trigger, returning Sakashima the Impostor from your graveyard to the battlefield as a copy of Havi.
4. Resolve the Sakashima the Impostor trigger, returning any legendary creature card with mana value 5 or less from your graveyard to the battlefield.
5. Resolve the Yahenni ability.
6. Repeat.

This intricate loop hinges on Havi, the All-Father, whose death trigger lets you resurrect a lesser-mana legendary creature whenever a legendary creature you control perishes. By using Yahenni, Undying Partisan as your dedicated sacrifice outlet, you send Sakashima the Impostor straight to the graveyard—triggering Havi's resurrection ability. Because Sakashima the Impostor is legendary, its own dying trigger goes on the stack alongside Havi's, allowing you to cycle through any legendary creature card with a mana value of 5 or less while perpetually bringing back Sakashima the Impostor to restart the cycle.
