Crash and Burn

A modal removal spell built for a set with a Vehicle problem to solve. The Vehicle mode is the tell: a hard artifact-destruction option grafted onto a burn spell exists because Vehicles are creatures only when crewed, so a spell that reads only "destroy target creature" whiffs on an uncrewed one sitting on the battlefield waiting. The first mode answers a Vehicle whether or not anyone is aboard; the second is a straightforward six-damage bolt aimed at the creatures and planeswalkers that a Vehicle-light board actually fields. That split is the whole design logic: one spell that covers both halves of a mechanic that toggles between artifact and creature, at a cost that would be aggressive for either mode alone if the rate were tighter. What you pay for the flexibility is the four mana and sorcery-cost feel, though it fires at instant speed, so it holds up as a combat trick against an attacking Vehicle or catches a planeswalker the turn it lands. Six damage is a deliberately high ceiling: it clears the fatties that shrug off three, and the modality means the card is rarely a dead draw, since almost every board presents a legal target for one line or the other.
