This ingenious loop relies on Woe Strider to act as the permanent sacrifice outlet that keeps the engine running, while also bringing along a Goat token to help kick things off. By feeding The Master, Formed Anew: Body Thief to Woe Strider's activated ability, The Master heads to the graveyard and triggers its own copied text—which now reads as Driver of the Dead thanks to its exile-and-copy effect. That Driver of the Dead trigger targets The Master itself in the graveyard, bringing it right back to the battlefield as a fresh copy of Driver of the Dead ready to be sacrificed to Woe Strider all over again.
