This lethal tango begins once Enduring Angel has already transformed into Angelic Enforcer, whose power and toughness scale directly with your life total. When you send Angelic Enforcer into the red zone, its attack trigger immediately doubles your life total. That sudden surge of life is caught by Defiant Bloodlord, turning every single point of gained life into an equivalent loss of life for your target opponent. Because Angelic Enforcer's massive power ensures the resulting life loss completely drains your foe down to zero or less, you close out the game in a single devastating strike.
