Saffi Eriksdotter + Extraction Specialist + Phyrexian Altar

Saffi Eriksdotter

Extraction Specialist

Phyrexian Altar

How it works

1. Activate Saffi by sacrificing it, targeting Extraction Specialist.
2. Activate Phyrexian Altar by sacrificing Extraction Specialist, adding one mana of any color.
3. When Extraction Specialist dies, Saffi triggers, returning Extraction Specialist from your graveyard to the battlefield.
4. When Extraction Specialist enters the battlefield, it triggers, returning Saffi from your graveyard to the battlefield.
5. Repeat.

This clever loop turns Saffi Eriksdotter and Extraction Specialist into a self-sustaining recycling team fueled by Phyrexian Altar. By sacrificing Saffi to target Extraction Specialist, and then sacrificing Extraction Specialist to the Altar for mana, you trigger Saffi's delayed effect to bring the Specialist right back. In turn, the returning Extraction Specialist uses its entry ability to pull Saffi back out of the graveyard and onto the battlefield, ready to start the cycle all over again.
