Shrink

A green combat trick that only moves one of the two numbers, and the wrong one. Pumping power is green's whole vocabulary in combat; reducing an attacker's power is a defensive maneuver that lives more naturally in white or blue, and even there the standard tool was tapping or fogging rather than shaving offense. For one mana you turn an incoming threat into something that hits for five less, which reads efficient until you notice what the card refuses to do: it leaves toughness untouched, so it kills nothing on its own and only blunts a single attack. The -5/-0 is large enough to neutralize most early creatures' damage entirely, but only for that turn, and only against power, never against an opposing combat trick that adds toughness or against a creature you would actually want dead. It is a reactive answer to a specific problem (a fat attacker you cannot block profitably) shipped in the color least equipped to follow up on the tempo it buys. The design reads like an experiment in giving green a purely defensive instant, a role the color has spent most of its history rejecting in favor of bigger bodies and combat math that favors the attacker.
