Saffi Eriksdotter + Eternal Witness + Aluren + Woe Strider

Saffi Eriksdotter

Eternal Witness

Aluren

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 Aluren.
7. Repeat.

This elegant loop turns a graveyard into a revolving door by leveraging the cost-reducing enchantment Aluren to cast Saffi Eriksdotter for free whenever she returns to your hand. Woe Strider provides a reliable sacrifice outlet to send Eternal Witness to the grave, which simultaneously triggers Saffi's delayed return effect and prompts Eternal Witness to fish Saffi right back out. Because Aluren lets you recast Saffi at instant speed for zero mana, you can repeat this cycle endlessly to fuel infinite sacrifices, enters-the-battlefield triggers, and continuous scrying.
