Devout Decree

Exile is white's premium removal mode, the one it reserves for threats too resilient to shrink with a Pacifism or wall off with a Journey to Nowhere. Handing that out unconditionally at this rate would trample every other answer in the color, so the target gets fenced in twice over: it must be a creature or planeswalker, and it must be black or red. That double gate turns a clean, no-strings exile into a wedge aimed squarely at aggressive red creatures and grindy black midrange. Against a white, blue, green, or colorless board it is a dead draw, and because the spell needs a legal target on resolution, you cannot even fire it for the scry alone when nothing black or red is in reach. That binary is exactly the point: it trades universality for a sharp rate against half the color pie. The scry rider is not compensation for a card left stranded in hand (a color-conditional answer already dead in hand stays dead); it is the small dividend the card pays out once it does connect, smoothing the next draw after you have committed the spell to a target worth exiling. It belongs to the family of hate cards that buy their efficiency by narrowing the pool of things they can hit, and it commits to that trade without apology or hedge.
