Noble Vestige

Damage prevention as a recurring tax is the design idea here, and the math is deliberately small. One point per activation, capped at the next single point that would be dealt to a player or planeswalker, prevented one tap at a time: this is a fog reduced to its homeopathic minimum. The intent is to irritate an aggressor rather than wall one out, soaking up the trickle of one-power attackers, shock effects, and incidental burn that white's broader prevention shields once handled in bulk. The targeting clause is what gives the activation its shape: it protects the player or a planeswalker, never a creature, so the Vestige cannot be turned into a combat shield for its own team. It is a survival valve, not a defensive trick. The flying body does the honest work of trading or blocking while the tap ability shaves a point off whatever clock is ticking down your life total or a walker's loyalty. Prevention scaled this finely rarely swings a single game; the design knows it, and the value sits in the repetition: a permanent that quietly subtracts from every burn-based plan that assumes it can count to twenty (or to a planeswalker's starting loyalty) without interference. A Spirit that taxes the last point of reach, turn after turn, for as long as it survives.
