Think many mentions here are not one trick ponies but footballers with trademark moves. Robben e.g. had so much more to his game than his cutting inside.
If we are talking about trademark moves:
Iniesta/Laudrup: La croqueta
Kroos/Herrera: First touch shuffle
Lahm/Nainggolan: Backheel tackle
Quaresma/Rosicky: Outside of the foot crosses/shots
Busquets: Fake pass
Özil: Passing/finishing by bouncing the ball into the pitch
Cruyff: Cruyff turn
Zidane: Roulette
Ronaldinho: Elastico
Robinho/Cristiano: Step overs
Maradona: Overhead crosses
Ronaldo: Rounding the keeper
Messi/Raul: Lobs over the keeper
Okocha/Neymar: Okocha flick
