Platinum Emperion

If a cost would include causing you to gain life (like the alternative cost of an opponent’s Invigorate does), that cost can’t be paid.

Effects that would replace having you gain life with some other event won’t be able to be applied because it’s impossible for you to gain life.

Spells and abilities that would normally cause you to gain or lose life still resolve, but the life-gain or life-loss part simply has no effect.
