Surge of Salvation

Two protective effects welded into one white instant, each aimed at a different kind of threat. The hexproof half is the universal clause: it lifts you and every permanent you control out of range of anything that has to choose a target, so pointed removal fizzles the moment it goes to resolve and burn thrown at your face has nowhere to land. The damage-prevention half is where the color pie shows its intent, and it is scoped hard: only black and red sources get blanked, the two colors white has always been drawn up to resist along the aggro-burn axis. That narrow targeting does the balancing work. Blank every damage source and this becomes a defensive answer to any board; confining the prevention to black and red instead makes it lopsidedly punishing against swarms and reach-burn while leaving green stompers and mirror-white weenie untouched. Note the second limit hiding in the wording: the prevention shields only creatures you control, so it is combat and mass-damage insurance rather than a blanket. Against a black or red board, that buys a clean combat step: your blockers survive the exchange, your team walks out of a red board sweep intact, and the surgical removal the hexproof clause catches was never going to connect anyway. One white mana that answers two shapes of threat at once, without pretending to hold a line against green or white.
