Affinity for artifacts
Artifacts you control have "{t}: Add {w}. Spend this mana only to cast an artifact spell."
At the beginning of the end step of a turn you cast a white artifact spell, gain 1 life. At the beginning of the end step of a turn you cast an artifact spell that wasn't white, lose 1 life.
"Your actions dictate the consequences."
