Saffi Eriksdotter + Eternal Witness + Aluren + Blasting Station

Saffi Eriksdotter

Eternal Witness

Aluren

Blasting Station

How it works

1. Activate Saffi by sacrificing it, targeting Eternal Witness.
2. Activate Blasting Station by tapping it and 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 and Blasting Station trigger.
5. Resolve the Eternal Witness trigger, returning Saffi from your graveyard to your hand.
6. Resolve the Blasting Station trigger, untapping it.
7. Resolve the Blasting Station ability from step 2, dealing 1 damage to any target.
8. Cast Saffi by paying 0 due to Aluren.
9. When Saffi enters the battlefield, Blasting Station triggers, untapping it.
10. Repeat.

This loop is a masterclass in recursion, turning the graveyard into a revolving door that deals infinite damage to your opponents. Aluren does the heavy lifting by letting you cast Saffi Eriksdotter for free at instant speed, while Blasting Station provides the sacrificial outlet and the win condition, untapping itself every time a creature enters the battlefield. By sacrificing Saffi to protect Eternal Witness, and then sacrificing Eternal Witness to Blasting Station, you set off a chain reaction where Eternal Witness brings back Saffi from the graveyard to your hand, and Saffi brings back Eternal Witness from the graveyard to the battlefield.
