Why do people waste their time attacking the Smashville balloons and Duck Hunt birds?
I always see people in tournament matches attacking the balloons and birds, and I wonder why... in high-pressure situtuations, doesn't it just waste time?
A lot of people don't because of what you mentioned, it wastes time and can possibly be punished. However, it adds new moves and pushes out old ones from the nine-move staling list, which can be useful for unstaling a smash attack for killing.
