On spacies, if I'm not going to get caught under a platform I like to use d-throw up-smash into a dashing grab. This usually pins them nearer the edge of the stage for a d-throw tech-chase while I await the return of my Nana.
Another goofy one is d-throw u-air. Use the soft hit of u-air and they go basically nowhere, except since it's trying to send them up they don't get to smash DI into the ground.
