This clever recursion loop turns a humble one-drop into a relentless engine of destruction by leveraging the passive generation of both mana and bodies. Whenever you feed Bloodsoaked Champion to Goblin Bombardment, Pitiless Plunderer immediately refunds your investment in the form of a Treasure token while Bridge from Below stocks your board with a 2/2 Zombie token to sustain the sacrifice chain. By sacrificing that leftover Zombie to Goblin Bombardment as well, you trigger Pitiless Plunderer a second time to easily generate the exact amount of mana needed to satisfy Bloodsoaked Champion's raid cost. The result is an endless cycle of sacrifice, damage, and rebirth that effortlessly closes out games.
