Keening Apparition
Most enchantment removal asks you to pay a card and some mana up front for the privilege of answering a threat that may not be on the board yet. This Spirit folds that cost into a creature a beatdown deck was probably willing to run anyway: a 2/2 body that pressures life totals while it waits, then converts into a Disenchant the moment an enchantment worth destroying resolves. The sacrifice cost is the wrinkle that makes the design honest. The answer is locked behind the creature's continued existence, so a removal spell or a chump block on the wrong turn strips the safety valve before you can fire it; and because it is an activated ability with a sacrifice cost rather than an enters-the-battlefield effect, you can hold it open and pay the price at instant speed, but only after you commit the body to the board. White has a long tradition of stapling utility onto small creatures so an aggressive deck never has to dilute its curve for an answer it might not need, and this one sits squarely in that lineage: it trades the rate of a dedicated spell for a clock that does nothing wasted if the opponent never plays an enchantment. The body is the floor, the ability is the ceiling, and the player decides which one they bought based on what the opponent does.
