method with zelda: if you use hold targeting you can use the old pause buffer setup, theres a bunch of tutorials on youtube for it

with switch targeting: target zelda in the corner, untarget and turn almost 90 degrees so zelda in no longer in target range. change direction to left ess then turn until you see a frame like this http://i.imgur.com/xv9CDlS.png look for links ear almost lining up with the railing. Then simply switch from ess left to ess right and you should clip. remember to keep holding right until you hit the loading zone.

for without zelda: line up with the railing next to the corner where you clip, do a right sidehop sideroll into the corner and crouch stab to get away from the wall. turn around, pull a bomb and start a hess. look for a frame that looks like this http://i.imgur.com/CoMzw40.png notice links ear lined up with the 2nd bar on the railing. from here, pause, let go of Z and hold up, advance 2 frames, then unpause and hold right and you should clip.
