Road Rage

Two damage for one red mana is Shock's rate, and Shock is the anchor: this burn spell starts exactly where the baseline sits and climbs from there. The wrinkle is what it counts. Rather than tying its ceiling to lands, creatures in general, or graveyard size, it reads the board for a specific pair of permanent types, so the payoff only comes alive when you are already fielding Mounts and Vehicles. That is the entire balancing act. Without them, you have paid one mana for a Shock that also reaches planeswalkers, which is a fine floor and a dull one; with them, each relevant permanent pushes the burn a point higher, and instant speed lets you cash the count during combat or in response to a blocker. It sits in the small family of removal that rewards a type-matters build rather than raw efficiency, with one twist: the counted permanents are the artifacts and creatures a red-leaning aggressive deck already wanted to run. The design folds a subtheme back into damage output, so the deck's utility bodies double as multipliers on a removal spell that otherwise asks for nothing. The one thing it cannot do is close the game itself, since it never touches a player's life total; every extra point stays pointed at the board.
