Disa the Restless + Altar of Dementia + God-Eternal Rhonas + Maskwood Nexus

Disa the Restless

Altar of Dementia

God-Eternal Rhonas

Maskwood Nexus

How it works

1. Activate Altar of Dementia by sacrificing God-Eternal Rhonas.
2. When God-Eternal Rhonas 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 Rhonas's power, which will cause you to mill God-Eternal Rhonas.
4. As God-Eternal Rhonas is a Lhurgoyf due to Maskwood Nexus, Disa's first ability triggers, returning God-Eternal Rhonas from your graveyard to the battlefield.
5. When God-Eternal Rhonas enters, it triggers, doubling the power of other creatures you control until end of turn.
6. Repeat.
