I noted something really funny just now. Zamus' rapid jab is really good at putting a stop to Falco Phantasm (at least grounded ones). I did several tests, and no Phantasm damaged Zamus. A few passed through at no ill to Zamus, and some were stopped dead by the jab.
(Other rapid approach moves that this does well at interrupting are Luigi Cyclone, Rollout, Spindash, Snakedashing, Raptor Boost and Squall Hammer. All in all, the use is limited, but it's something to keep in mind, and may affect several matchups.)
