Focus Fire

White removal usually asks for something in return: an attack step, a life gain rider, a counter to justify the effect, or a permanent to sit on the board. This buys damage the way red does, at instant speed, but locks it to combat. The floor is two damage for one white mana, killable range for most early aggressors, and X climbs with your board, counting both creatures and Spacecraft. The combat clause is what pays for the scaling: it can only reach an attacker or a blocker, so a creature sitting back on defense is untouchable, and the spell becomes lethal against a fatty only once that fatty commits to combat while you hold a wide board. In a go-wide deck it reads like a burn spell, three, four, five damage pointed at the biggest thing the opponent dares to swing or block with, converting a defensive answer into a punish for engaging at all. The design gives white the reach it structurally lacks: scaling removal that rewards the exact board state white already wants to assemble, without handing the color unconditional point removal at instant speed. The Spacecraft rider ties it to an artifact-adjacent shell, but the core is older than that count: a white weenie payoff that answers the mirror's biggest creature by tallying your own army.
