OK, let's start the speculation - which one is the misterious Trophy listed in Trophy overview with 3 questionmarks and no colour?

Dear gentlemans and ladies, track your acomplishemnts and trophies so this fine community can see what is the secret one. Thank you in advance.

The secret trophy might be: Win a full deck Challenge Card Game!

Why would they keep the platinum trophy a secret! No other game does...(i think)...
