I think most Black decks will realistically be able to trigger this once or twice a game, and thats really all you need for this to pull its weight
I should also mention Stitcher Geralf, which is an on-flavor piece of semi-graveyard hate when needed
Quite a nice card to go with Illusory Angel although not a reason to earn it a cube slot
Thats about all I have to say about life gain for today
I rate this as one of the best spot removal spells you can play in a UW based control deck behind only the premium one mana cards, Winds of Abandon, and perhaps Wingshards if you count that as spot rather than mass removal
