This delightfully sinister loop turns a modest board state into an endless engine of destruction, fueled entirely by the color-shifting magic of Darkest Hour. Because every creature on the battlefield is now black, whenever you sacrifice a creature to Goblin Bombardment, Teysa, Orzhov Scion sees a black creature die and immediately replaces it with a fresh 1/1 Spirit token. That token is also black, allowing you to feed it right back into Goblin Bombardment to repeat the cycle indefinitely for infinite damage and sacrifice triggers.
