Truck Toss

Fireball rates have always been the wrong lens for a four-damage burn spell: at for four to any target, this is a fine finisher and an unremarkable answer. The conditional discount is the interesting part. Control a Vehicle and the price drops to , turning a middling four-mana instant into a two-mana burn spell that outclasses almost everything at that rate. That is the whole tension. Running Vehicles costs you crew and board commitment, and this spell pays back that investment with premium reach that only functions when your permanents are pulling in the same direction. Unlike the endless line of red spells discounted by an artifact you already wanted (affinity, improvise, and the like), the reduction here is narrow enough to be a genuine deckbuilding demand rather than incidental gravy: you either build around Vehicles or cast an overpriced Fireball. The discount is a static ability checked as you cast, not a trigger, so it reads your board the moment you put the spell on the stack: resolve your threats first, then lean on them for reach. That sequencing is the point. A deck built to keep a Vehicle in play converts otherwise dead mid-combat cards into instant-speed burn, which is the aggressive red-artifact plan this spell is engineered to reward. The full-price rate is the floor; the two-mana rate is the reason to build around it.
