Life Doubler

Cards carrying a replacement effect that reads, in essence, if you would gain life you gain twice that much instead, amplifying every other life-gain source in your deck. Rhox Faithmender, Boon Reflection, and Alhammarret's Archive all turn modest gains into large swings, and they stack multiplicatively when more than one is in play. Distinct from Lifegain Source, which actually produces the life, this set only multiplies gains that something else generates; with no other gain in play these do nothing. Also distinct from Lifegain Payoff, which triggers off the gain event for some other reward rather than increasing the amount gained.
