Explosive Derailment

Red's flexible early removal used to force a choice at deckbuilding: run Abrade and accept that when you needed both a dead creature and a dead artifact, one card was never going to cover both. This unbundles that math. The mana line shows a single red, but Spree makes that a floor you can never actually pay, because at least one mode is mandatory. Pick one and you have spent for four damage or artifact destruction, sitting right in the neighborhood of the old modal instants. Pick both and you have spent to answer a creature and an artifact off one card, at instant speed, in a single window. The rate to do one thing barely moves; what moves is the rate to do everything, and the second half is a purchase you make only on the turn it pays. That structure changes how you hold it: a modal instant wants to be spent on the first threat that walks in, but this one rewards patience, sitting in hand until a board actually presents both an artifact and a creature worth burning. What keeps the two-for-one from being free is the additional per mode: the coverage is broad, but you pay for exactly as much of it as you use, at the moment you use it.
