Cliffside Rescuer

Protection has always been the most complete answer white owns: a permanent with protection from your opponents cannot be blocked, targeted, damaged, enchanted, or equipped by anything they control. What this Kor Soldier does is convert its own body into that shield on demand, tapping and sacrificing to wrap any permanent you control in a full turn of immunity. The flexibility is the point. Because the ability reads "permanent you control," the same activation saves an enchantment from a Disenchant, walks an attacker through a lethal blocker untouched, or protects a mana rock from a shatter effect at the moment it matters. The design leans hard on timing: the ability is instant-speed, so when an opponent puts a removal spell on the stack and passes priority to you, you can respond, spending a two-mana body only once you know precisely what your opponents mean to destroy. The cost is the creature itself, which makes this a single, decisive use rather than an ongoing engine: once spent, the insurance is gone. Vigilance is the quiet enabler here, letting it attack for its two power without tapping down, so the sacrifice ability stays live on the crack-back turn instead of being locked away by a swing. It sits in a lineage of dedicated white protection pieces going back to the color's earliest insulating keywords, refined here into a one-shot answer you keep in reserve and cash in for exactly one crisis.
