White's lifegain decks have always faced the same awkward question: what do you do with all that life once you have it? Most of the cards that produce it (incidental gainers, lifelink bodies, prison enchantments) are good at hoarding the resource and bad at spending it. Here is one of the few payoffs that converts the pile directly into evasive power, scaling the army to whatever total you have banked. Resolve it at twenty life and you get twenty fliers, already a closed game; in a shell that has gained its way to forty or sixty, it stops being a finisher and becomes the entire win condition, the moment lifegain flips from a defensive subsystem into a damage clock. That conversion is the design idea, and it is rare precisely because rewarding the life total itself, rather than the creatures or enchantments that generated it, is hard to do without breaking the math. The cost is steep and the timing is honest: ten mana at sorcery speed, no flash, no trick, so it demands you survive to a turn where the mana and a fat life total coincide rather than promising a cheap blowout. The flavor tracks the arithmetic cleanly, the cavalry growing with the strength you have left to spend. It is a top-end haymaker built for a single archetype, and inside that archetype it does something almost nothing else does.
