This infinite loop relies on a devastating feedback loop between Defiant Bloodlord and Bloodthirsty Conqueror. Once you trigger the cycle by gaining life from any source, Defiant Bloodlord immediately responds by draining an opponent's life total. That loss of life prompts Bloodthirsty Conqueror to grant you life in return, which instantly restarts Defiant Bloodlord's trigger and creates an unstoppable loop that closes out the game on the spot.
