Crackdown

White's answer to the big-creature problem, built as a tax on size instead of a kill spell. It draws a clean line at power three and leaves every nonwhite body above it locked: a 3/3 or larger nonwhite attacker can swing, but afterward it sits, never untapping during its controller's untap step, until the enchantment is gone. The threshold is the whole design. It separates the small evasive creatures white likes from the fatties the color is meant to struggle against, and it pointedly spares white's own beefy creatures, so a white-based deck can run it without hamstringing itself. The effect is a static prison rather than a single answer to a single threat, which makes it a hard wall against ground-stall midrange and ramp-into-fatties strategies and nearly useless against weenie swarms or anything that goes wide under the line with two-power bodies. Most white removal from the same era either fought individual creatures or punished attackers; this reaches an entire category at once and keeps reaching it as long as it stays on the board. It is a piece of color-pie engineering: an enchantment-based lock that white earned by aiming it squarely at the board states the color is supposed to lose to, while leaving the creatures white actually wants to play untouched.
