This engine transforms a simple sacrifice loop into a ceaseless factory of value by leveraging the graveyard as a revolving door. Woe Strider acts as the sacrificial outlet, letting you feed your creatures into the graveyard while utilizing its scry ability to smooth your draws. Whenever a creature meets its end, Nether Traitor's triggered ability lets you immediately pay {B} to bring it right back to the battlefield, constantly feeding the graveyard and triggering the loop. Meanwhile, Kheru Goldkeeper and Garrison Excavator sit quietly watching your graveyard, automatically spitting out a Treasure token and a 2/2 Spirit token every single time cards leave your graveyard. By sacrificing the newly minted Treasure for the black mana needed to revive Nether Traitor, the entire loop becomes self-sustaining and endlessly repeatable.
