The cards abilities only trigger with PW's abilities to deal damage and are not triggered by creatures, spells or support making the Masterpiece almost worthless.

are you using cards that specifically say loses life in their text? ob nixilis, captive kingpin triggers when the opponent loses life, not when the opponent takes damage. creature damage and cards that say deals damage won't trigger it.
