Screw Attack out of shield really annoys the spacies in close range. Use ftilt or jab combo to get them off-stage then gimp. Simply edgehog Wolf, grapple hog if necessary. Force Falco to illusion, and catch him with zair or uncharged shot. He will then be forced to use Fire Bird, edgehog it or spike. Fox is a bit harder, zair the illusion and try to spike the firefox, even if he's off the bottom of the screen. Samus' recovery is amazing so you can make it back. Spacies are known for their great aerial approach game, so keep your spacing good.
