Defensive Stance

The math is the whole point: shift a creature's stats by one in each direction and you neuter its offense while making it stubborn on defense. A 2/2 becomes a 1/3, a 3/3 a 2/4, and suddenly the attacker your opponent invested in is a wall that trades down or simply stays home. This is pacifism by attrition rather than pacifism by fiat: where harsher Auras switch a creature off entirely, this one leaves the body functional but rebuilds it into something useless to an aggressor. The trade you accept is that nothing dies and the toughness boost can occasionally backfire, propping up a creature you would rather have left in burn range. As an Aura it asks for a sorcery-speed commitment with no card advantage to show for it, which puts it in the lineage of cheap blue answers that buy tempo by taxing a creature's role rather than removing it. It is a small, honest piece of design: an answer scaled precisely to the creatures it was built to embarrass, the aggressive low-toughness bodies that lean on their power and have none to spare. Against anything that wants to attack, the minus-one to power is the whole transaction; against anything already content to block, it accomplishes nothing, which is exactly the boundary a one-mana effect like this should respect.
