I cannot explain to you why contact-fuse or fusion can use face-down monsters; while you can't synchro face-down monsters. You know you can treat a face-down "Kaiser Sea Horse" as 2 tributes while "Skill Drain" is on the field? It is just pure rulings, game mechanics.
However for Mask change it activates by targeting a "HERO" monster, a face-down monster does not have a name.
