Gleam of Authority

Most counter payoffs read your board once and pay out; this one is a recursive loop that funds itself. The host grows by the total of every +1/+1 counter sitting on your other creatures, and it carries its own way to make more of them: a repeatable ability that lets you pay the white and tap to bolster your smallest creature. Most activations feed the counter they just placed back into the host's size (unless the counter lands on the host itself), so the Aura is at once the meter and the pump that moves the needle. Bolster's selection rule is the wrinkle that keeps the growth from stacking onto one threat: it hands the counter to whichever of your creatures is currently frailest rather than a target you choose, so the spread it builds trends wide rather than tall, and a wide spread is exactly what the host wants to be counting. Vigilance is the quiet glue: the enchanted creature can attack as a finisher while remaining untapped for the next bolster, so swinging never costs you an activation. The whole design presumes a go-wide counter board, where it behaves less like a single buff and more like an anthem that scales off its own output. The standing objection to any Aura (it dies with its creature, two-for-one) is the price this rate is built around, and the payoff is a threat that assesses your entire board and turns it into a single number.
