Fire at Will

Three damage divided freely is a rate the sorcery-speed burners already offer: Arc Lightning and Flames of the Firebrand hand out the same points across the same number of bodies, asking only that you wait for your main phase. The trade here is the inverse: surrender the freedom to fire it whenever, and you buy back instant speed, but only inside combat. The targeting clause is the whole constraint, restricting every point to attacking or blocking creatures, which means the spell sits dead in hand until creatures are committed and then ambushes the swing. From behind, it kills before blocks are assigned or after they are locked, rewriting the math the attacker thought was settled. On your own attack, it clears the path mid-step. The free division gives it two faces at one cost: three points spread across three bodies blunts a go-wide alpha strike, while three points stacked on one creature is plain removal when that is all the board demands. This is a reactive punish, not a proactive answer. It holds mana for the declare-attackers or declare-blockers step rather than the main phase, and it never sets the pace, because it only ever responds to commitment. The sorcery versions match it for raw points and target count; what they cannot do is wait until the attacker has shown their hand and then collect the value at the exact moment combat math turns on it.
