Disa the Restless + Altar of Dementia + Arcane Adaptation + God-Eternal Oketra

Disa the Restless

Altar of Dementia

Arcane Adaptation

God-Eternal Oketra

How it works

1. Activate Altar of Dementia by sacrificing God-Eternal Oketra.
2. When God-Eternal Oketra dies, it triggers, putting itself from your graveyard into your library.
3. Resolve the Altar of Dementia ability, causing you to mill cards equal to God-Eternal Oketra's power, which will cause you to mill God-Eternal Oketra.
4. As God-Eternal Oketra is a Lhurgoyf due to Arcane Adaptation, Disa's first ability triggers, returning God-Eternal Oketra from your graveyard to the battlefield.
5. Repeat.

This brilliant loop transforms Disa the Restless into an engine of endless rebirth by leveraging Arcane Adaptation to rewrite the creature types of your entire deck, turning God-Eternal Oketra into a Lhurgoyf. With that type-changing magic in place, sacrificing God-Eternal Oketra to Altar of Dementia mills your library—and because the God-Eternal’s own triggered ability puts itself into your library right into the path of that mill, it quickly ends up in the graveyard from outside the battlefield. That graveyard transition triggers Disa the Restless's first ability, instantly pulling God-Eternal Oketra right back onto the battlefield so you can repeat the sacrifice all over again.
