Quicksilver, Pietro Maximoff

The character comes with an ability built into his name: he is the fastest man alive, and the design resolves that concept the only sensible way, by handing him haste and stepping back. A 3/2 that attacks the moment it hits the battlefield is the plainest possible rendering of speed, and the card refuses to clutter it with a mutation trigger or a phased blink to gesture at his powers. That restraint is the point. A red three-drop that hits for three on arrival is a rate a hundred earlier bodies have shared; what distinguishes this one is that the flavor and the mechanic collapse into a single keyword rather than fighting each other. As a red creature meant to head a table or fill an aggressive slot, it does exactly what its cost and body promise and nothing beyond that. There is no engine to assemble and no build-around waiting underneath, which makes it an honest inclusion where a deck wants early pressure and a legendary body to lean on, and a plain one everywhere else.
