So obviously Shujinko gained a bunch of moves to copy, new ones in almost every matchup. But essentially he himself gained a few new special inputs. The DLC had some more copied moves than the normal cast like this but I'm not sure if it was listed in the move list, but anyway, he now technically has more specials listed in the move list. Every character has Mimic and Kopy Kat, some have 3 moves total, most have four. Sometimes there are variations of the same move.(EX Shang single skull, double, triple)
Mimic DBK (Half kameo bar for DB moves)
Kopy Kat DFK (Full kameo bar for DF moves)
(Depending on the matchup)
Steal DFKU
Replikate DFKD
Imitate DBKU
Flatter DBKD
