Turn the Tables
Most white damage answers blunt an attack: a Fog wipes the turn, removal shrinks the board, a blocker trades down. This one fogs and punishes in the same breath. Every point of combat damage that would land on you this turn, whether it comes from one giant attacker or a wide swing of five, is gathered up and dealt instead to a single attacking creature of your choice. You take nothing; one of theirs eats the whole bill. Against an alpha strike that means the attacking team becomes the fuel that kills its own biggest threat, and against a lone haymaker it means the creature swinging for lethal commits suicide.
The instant-speed window is where the card earns its tax. You sit on five mana, let the opponent commit to an attack that looks profitable, then redirect the entire damage step onto whatever target hurts them most: their finisher, their commander, the creature carrying every counter. The five-mana cost and the single-target restriction are the honest limits; you spend a full turn holding up a reactive instant, and you only get to nuke one creature even when the redirected total would have killed three. What separates it from a plain Fog is the emotional register. Surviving an attack is one thing; converting an opponent's overcommitment into the death of their best creature, with their own damage as the murder weapon, is a different and rarer kind of white trick.
