Golem's Heart
Artifact
Whenever a player casts an artifact spell, you may gain 1 life.
The heart of a golem gives life to more than just the iron husk around it.

Whenever a player casts an artifact spell, Golem’s Heart’s ability triggers and goes on the stack on top of it. It will resolve before the artifact spell does.

Unlike Golem Foundry and the Smith cycle, Golem’s Heart’s ability triggers whenever any player casts an artifact spell, not just when you do.
