Whenever a player casts a black spell, you may gain 1 life.
Its curve mimics the twists of life and death.

If a player casts a black spell, Demon’s Horn’s ability triggers and is put on the stack on top of that spell. Demon’s Horn’s ability will resolve (causing you to gain 1 life) before the spell does.
