Pious Kitsune

Devotion counters accumulate at the slow pace of one per upkeep, and the card spends them in two directions that fight each other. Passively, with Eight-and-a-Half-Tails on the battlefield, every counter pays out a point of life each turn the moment it arrives, so the engine rewards letting the stack grow untouched. The activated half lets you cash a single counter for a single life at will, draining the same reservoir the passive trigger feeds on. The result is a life-gain dial that scales with patience, but only if you have the named partner online: a design that hardwires one specific creature into another specific creature's text box by name. That dependency is the whole shape of the thing. Without Eight-and-a-Half-Tails, the upkeep trigger still stacks counters but does nothing with them, leaving a 1/2 body that taps to convert stored time into a slow trickle of life. The named-pair construction harks back to a design vintage when flavor partnerships were enforced by direct reference rather than by tribe or keyword, asking you to assemble a particular two-card combination before either piece earns its place. Slow, narrow, and entirely contingent on a friend showing up, it reads less as a standalone creature than as half of a sentence the rules text refuses to finish on its own.
