Supernatural Stamina + Phyrexian Altar + Returned Pastcaller

Supernatural Stamina

Phyrexian Altar

Returned Pastcaller

How it works

1. Cast Supernatural Stamina by paying , targeting Returned Pastcaller.
2. Activate Phyrexian Altar by sacrificing Returned Pastcaller, adding .
3. When Returned Pastcaller dies, it triggers, returning it from your graveyard to the battlefield.
4. When Returned Pastcaller enters the battlefield, it triggers, returning Supernatural Stamina from your graveyard to your hand.
5. Repeat.

This clever loop turns a modest bird into an engine of continuous recursion, utilizing Supernatural Stamina to grant the necessary afterlife insurance to Returned Pastcaller. Once you sacrifice the Pastcaller to Phyrexian Altar for a black mana, its death triggers its return while simultaneously letting its entry ability fish the Supernatural Stamina right back out of your graveyard. Because the Altar fuels the exact cost of the spell needed to keep the cycle going, you get a closed loop that generates infinite sacrifice and death triggers without ever dropping the combo.
