This ingenious loop relies on a clever creature transformation and a recursive graveyard return to exploit the sacrifice outlet of Bartolomé del Presidio. By using The Master, Formed Anew to copy Driver of the Dead, you create a self-sustaining engine where sacrificing The Master triggers the Driver's ability to bring it right back to the battlefield. Because The Master retains its copy effects or can re-enter to continuously cheat the mana value restrictions, this pairing generates infinite death triggers and creature sacrifices while your board state snowballs.
