Morophon, the Boundless + Saffi Eriksdotter + Eternal Witness + Goblin Bombardment

Morophon, the Boundless

Saffi Eriksdotter

Eternal Witness

Goblin Bombardment

How it works

1. Activate Saffi by sacrificing it, targeting Eternal Witness.
2. Activate Goblin Bombardment 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 Goblin Bombardment ability, dealing 1 damage to any target.
6. Cast Saffi by paying 0 due to Morophon.
7. Repeat.

This loop turns your graveyard into a lethal, self-sustaining engine by exploiting a clever mana-cost reduction. With Morophon, the Boundless on the board naming Humans, Saffi Eriksdotter can be cast for free, allowing you to continually sacrifice Saffi to target Eternal Witness. You then use Goblin Bombardment to sacrifice Eternal Witness, which triggers Saffi's delayed effect to bring Eternal Witness right back. That returning Eternal Witness triggers its own ability to pluck Saffi back from the graveyard into your hand, and while the board churns through endless cycles, Goblin Bombardment converts those repeating sacrifices into infinite damage for the win.
