Cradle of Vitality

The conversion engine for a lifegain deck, built around a payoff most lifegain cards never bother to specify: not the act of gaining life but the amount. The wording is the whole strategic axis, because the counter haul scales linearly with the size of a single gain event. A trickle of one or two from a stray lifelink swing buys a counter or two and a tax; one large gain (a hefty lifelink hit, a Beacon of Immortality doubling, a single big drain) dumps that entire number onto one creature at once. The catch is in how the trigger reads: it fires per life-gain event and asks for each time, so a turn that gains life in many small bursts is the worst case, not the best. Six separate one-life triggers from a board of soul sisters are six independent triggers, each demanding its own , and you will rarely have the mana to convert them all. The lesson the wording teaches is to gain a lot at once rather than a little repeatedly. It sits in a lineage of "turn lifegain into a board" payoffs that white decks have circled repeatedly, and it remains one of the few that rewards the magnitude of a single gain rather than treating each life-event as a flat trigger. On its own it does nothing: a four-mana enchantment that watches your life total and asks for more mana before it acts.
