Slash of Light

Removal that scales with the board it's protecting is an old white idea, but the counting method here is unusually literal: two axes, creatures and Equipment, both of which a go-wide or aggressive-artifact build already wants to maximize for reasons unrelated to this card. That double-count is the design tension. On an empty board it does nothing; in a flooded one it kills almost anything, and it reads as a two-mana spell that punishes an opponent for letting your side of the table fill up. The Equipment clause is the part doing the real work: it lets a deck light on bodies still turn hardware into removal reach, so a build stacking artifacts can point a swelling arsenal at a blocker mid-combat rather than waiting to draw a burn spell. Because it targets at instant speed, it also functions as a combat trick, letting you count your attackers after blocks are declared and remove the biggest thing standing in the way. The ceiling is genuinely high and the floor is genuinely nothing, which makes this a payoff card rather than a maindeck staple: it belongs where volume is the plan and the damage figure is a byproduct of a board you were building anyway.
