This brilliant loop turns the unyielding devotion of Oathsworn Vampire into a self-sustaining engine of sacrifice and rebirth. Warren Soultrader provides the altar to harvest your creatures for Treasure, while Fleshtaker catches the falling essence of each sacrifice to grant you the vital life required to cast the Vampire anew from your graveyard. Meanwhile, Edgar Markov watches from the command zone, quietly fueling the process with his eminence ability by spitting out an extra Vampire token on every cast so you can sustain the mana and sacrifice costs indefinitely.
