Wrath of the Skies

The genius of the design is that X does double duty: it both sizes the sweep and prices it. You generate X energy, then choose how much to spend, and the amount spent sets the mana-value ceiling of what dies. That second decision point elevates it past the standard board wipe, which sweeps everything below a fixed line or nothing at all. Here the ceiling is yours to set: paying enough energy to catch a five-drop necessarily sweeps everything cheaper with it, so the dial is one of reach rather than selection. What it lets you do is spare an expensive board while clearing the cheap one, or read the table and decide in the moment exactly how high the guillotine falls. Because energy is a resource you keep, an oversized X banks the surplus rather than wasting it, quietly turning a one-shot sweeper into fuel for the rest of an energy-based deck. The color identity is orthodox white catch-all removal in the lineage of Wrath of God and Planar Cleansing: it answers artifacts, creatures, and enchantments alike, hitting permanent-based strategies broadly rather than surgically. What is new is the calibrated handle bolted onto the sledgehammer, a mana-value threshold set as it resolves rather than a menu of fixed modes. The sorcery speed keeps it honest, forcing the caster to commit on their own turn, and the double-white anchors it firmly as a control card rather than a splash.
