This clever loop hinges on the relentless resurrection engine provided by Yarus, Roar of the Old Gods, which catches Master of the Veil as it dies and immediately slips it back onto the battlefield face down before proudly flipping it right back up. That face-up trigger is the beating heart of the machine, letting Master of the Veil target itself to flip back down into the shadows, ready to be sacrificed to Goblin Bombardment all over again. While Yarus also grants your board haste and extra card draw when your hidden threats deal combat damage, here its recursion turning face-down deaths into instant rebirths turns Goblin Bombardment into an infinite, game-ending damage cannon.
