Exquisite Blood
Enchantment
Whenever an opponent loses life, you gain that much life.
Even as humans regained the upper hand, some still willingly traded their lives for a chance at immortality.

Rulings
If you and an opponent both lose life simultaneously, and this causes your life total to become 0 or less, you'll lose the game before Exquisite Blood's triggered ability can resolve.

Damage dealt to an opponent usually causes that opponent to lose life. An opponent paying life also causes loss of life.
