Defiler of Flesh + Aetherflux Reservoir + Gravecrawler + Altar of Dementia

Defiler of Flesh

Aetherflux Reservoir

Gravecrawler

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing Gravecrawler, causing target player to mill cards equal to Gravecrawler's power.
2. Cast Gravecrawler from your graveyard by paying 2 life.
3. Aetherflux Reservoir and Defiler of Flesh trigger.
4. Resolve the Aetherflux Reservoir trigger, causing you to gain 1 life for each spell you've cast this turn.
5. Resolve the Defiler of Flesh trigger, giving target creature +1/+1 and menace until end of turn.
6. Repeat.
7. Once you have infinite life, you may activate Aetherflux Reservoir's ability to deal infinite damage to any target(s).

This relentless loop hinges on Gravecrawler’s ability to repeatedly crawl back from your graveyard as long as you control a Zombie, while Defiler of Flesh steps in to make that recursion completely free by paying life instead of mana. As you churn through these castings, Aetherflux Reservoir tracks your storm count to balloon your life total with a steady stream of lifegain. Finally, Altar of Dementia converts your endless cycle of sacrifices into infinite mill, allowing you to stockpile more than enough life to cash out via Aetherflux Reservoir's lethal activation.
