Grave Researcher // Reanimate + Biblioplex Tomekeeper + Phyrexian Altar + Sultai Flayer

Grave Researcher // Reanimate

Biblioplex Tomekeeper

Phyrexian Altar

Sultai Flayer

How it works

1. Activate Phyrexian Altar by sacrificing Biblioplex Tomekeeper, adding .
2. Sultai Flayer triggers, causing you to gain 4 life.
3. Cast the copy of Reanimate from exile by paying , returning Biblioplex Tomekeeper from your graveyard to the battlefield and losing 4 life.
4. When Biblioplex Tomekeeper enters, it triggers, preparing Grave Researcher.
5. Repeat.

This recursive loop hinges on the synergy between Grave Researcher and Biblioplex Tomekeeper, where the Researcher's prepared status allows you to repeatedly cast Reanimate copies for black mana. You fuel this engine using Phyrexian Altar to sacrifice the Tomekeeper, which conveniently triggers Sultai Flayer to offset the life lost to Reanimate. When Biblioplex Tomekeeper returns to the battlefield, its entry trigger instantly prepares Grave Researcher anew, letting you loop the entire sequence for infinite sacrifices, lifegain, and death triggers.
