Expel the Interlopers
The dial is the whole point. Most white board wipes ask nothing of the caster beyond the mana: Wrath of God kills everything, Day of Judgment kills everything, and the symmetry is baked in. This one hands the sweeper a variable and makes the player set it. Choose 0 and you have a Wrath that also takes your own board; choose 4 and you leave the mana dorks and one-drops standing while the fatties die; choose 10 and you clip only the largest threats. That turns a binary reset into a scalpel with eleven settings, and the interesting cases live at the edges, where a token deck or a go-wide aggro plan sits entirely under the chosen number and walks away untouched while the opponent's midrange bodies get swept. The design tension is that power, not toughness, is the axis, so a defensive wall with high toughness and low power survives a high setting that a bigger attacker does not: the number you name is a read on which half of the board you can afford to keep. It is a sweeper for a player who knows exactly what is on the table and wants to cut cleanly through it, which is a different job than the reset button white has printed for decades. The cost of that precision is the read itself; name the number wrong and you have paid five mana for a worse Wrath.
