well theres alot of recovers for samus. first of all, are you doing the advance techniques like shffling, upb out of shield, short hop sex kick out of shield, using missle cancels instead of standing missles. the way i play against characters who don't have projectiles or reflectors is I do many short hops and shoot smash missles, and as they come they will most likely go for an air attack. so when they're close enough do a uair then fair then l cancel that to a downsmash. that usually works unless they float out of it. but many other times when they jump, a sex kick from samus will usually take him out easily. Recover for samus. bomb jumping then shoot a missle equal to the platform. or try hooking the lower wall then wall jumping to up b/bair, it's extremely fast and hard to catch. If you're dropping high from the stage and you're still off of it try shooting homing missles. or get a charged shot. anyone who charges a smash knowing you'll go there you can just shoot one of those at them.
