In any match of strength, whether in real life or in a fighting video game, a person can rarely afford to stand still. This leads to one being susceptible to a flurry of possible attacks by an opponent, and this reigns no truer than in Arms. This is why a player should always be moving, shifting and changing their angles of attack to keep their opponents on their heels. It's all the more important to take advantage of a stage that provides changes in movement, further making your attacks all the unpredictable.
