Whack

A conditional discount aimed at exactly one color of creature. Priced against white specifically, the reduction collapses a clumsy four-mana kill spell into a one-mana answer the moment the target wears white, and offers nothing against anyone else. That asymmetry is the whole design proposition: read as a mediocre removal spell in a vacuum, it functions as color-hate tooling wearing generic black removal as a costume. The -4/-4 mode does its own quiet work, slipping past indestructible where a destroy effect would bounce off. What makes the card notable is how it encodes the punishment into rate rather than into a keyword or an exile clause. Older sideboard answers wore their function on their sleeve (a protection line, a named creature type in the text). This one names its target too (the discount clause says "white creature" outright), but it buries the hate in the mana cost rather than the effect: the spell still just gives -4/-4 to anything, and the color you are punishing only changes what you pay to do it. What limits it is that the enormous savings are purely defensive; you cannot bank them against a green creature or a colorless threat, so the card is only as good as the opposing color spread lets it be. Paid in full it is a fair, forgettable removal spell; aimed at the color it was built to punish, it becomes one of the cheapest single-target answers black has.
