Re-read the description. It is explicitly written that when he is filed, he displays many skills besides card throwing, yet that is the only one we have read about so far. Unless you think he knows those skills already, the logical conclusion is that the title is the end result or a transitional phase of the novel, not the beginning. Therefore, we will first read about him mastering card throwing, moving on to master a plethora of other skills, then being filed.
