Morophon, the Boundless + Saffi Eriksdotter + Eternal Witness + Woe Strider

Morophon, the Boundless

Saffi Eriksdotter

Eternal Witness

Woe Strider

How it works

1. Activate Saffi by sacrificing it, targeting Eternal Witness.
2. Activate Woe Strider by sacrificing Eternal Witness.
3. When Eternal Witness dies, Saffi triggers, returning Eternal Witness from your graveyard to the battlefield.
4. When Eternal Witness enters the battlefield, it triggers, returning Saffi from your graveyard to your hand.
5. Resolve the Woe Strider ability, causing you to scry 1.
6. Cast Saffi by paying 0 due to Morophon.
7. Repeat.

This intricate loop turns Saffi Eriksdotter and Eternal Witness into an immortal duo by constantly trading places between the battlefield and the graveyard. Woe Strider acts as the sacrificial outlet that triggers Saffi's life-saving return, while also letting you dig deep into your library with infinite scry 1 triggers. Meanwhile, Morophon, the Boundless works behind the scenes by naming Humans, neatly eliminating Saffi's mana cost so you can recast her infinitely for free.
