Falkenrath Forebear + Voldaren Bloodcaster // Bloodbat Summoner + Phyrexian Altar + Adrix and Nev, Twincasters

Falkenrath Forebear

Voldaren Bloodcaster // Bloodbat Summoner

Phyrexian Altar

Adrix and Nev, Twincasters

How it works

1. Activate Phyrexian Altar by sacrificing Falkenrath Forebear, adding .
2. When Falkenrath Forebear dies, Voldaren Bloodcaster triggers, creating two Blood artifact tokens.
3. Activate Falkenrath Forebear by paying and sacrificing the Blood tokens, returning it to the battlefield from your graveyard.
4. Repeat.

This loop is a masterclass in recycling resources, turning a single drop of black mana into an engine of endless sacrifices. When you sacrifice Falkenrath Forebear to Phyrexian Altar, its demise triggers Voldaren Bloodcaster to generate a Blood token, but the replacement effect of Adrix and Nev, Twincasters doubles that yield into two tokens. Those very tokens provide the exact mana and sacrifice requirements of {B} and two Blood tokens printed right onto Falkenrath Forebear to recur it from the graveyard, netting you an infinite loop of deaths and enter-the-battlefield triggers.
