This clever loop turns Woe Strider into a relentless sacrifice engine, using its ability to send Nether Traitor to the graveyard. Each time Nether Traitor hits the graveyard, its own ability lets you pay {B} to bring it right back, a cost easily paid by sacrificing the Treasure tokens generated along the way. While this core loop keeps turning, Kheru Goldkeeper and Chalk Outline act as your payoff engines, capitalizing on cards leaving your graveyard to flood the battlefield with infinite creature tokens, Clues, and mana.
