The only time I ever saw a slave cylinder result in a dead pedal was when it blew out and left all the fluid on the ground. I'd have to say your master cylinder is shot. This is assuming you have bled all the air out of the system.
Also, after bleeding a clutch system, the pedal must be pumped half a dozen times after the last time the bleed valve is opened, in order to build up the pressure in the line. The pedal requires back pressure of the fluid to force it back up.
