Fell the Mighty

Most board wipes draw a flat line: destroy everything, or everything of a type, or everything above a fixed mana value. This one draws the line wherever you point it. By keying the destruction to a creature's power rather than an absolute threshold, the card lets you set the cutoff at the table and then survive beneath it. Aim at your own smallest token or one-power dork and the sweep clears the opponents' fatties while your board sits safely at or below the line: a one-sided wrath that costs you nothing but the targeting decision. The price of that asymmetry is built into the targeting itself. You need a creature small enough to define a useful floor, the spell spares anything at or below that power, and a wide aggressive board full of low-power bodies can slip entirely under the cut. It punishes the tall decks (the voltron commanders, the reanimated giants, the stompy curve-toppers) and shrugs at the go-wide ones, which makes it less a panic button than a deliberate answer to a known shape of threat. That conditional, who-survives logic is the whole design: a removal spell that rewards reading the board and building a deck whose own power figures sit on the right side of the line.
