Magic Duels: Functions

This information is pulled directly from the executable. However, simply hexing the executable does not give much information about what function belongs to what object or where one object ends and another begins, nor does it give us information on parameters. As such this list may go through many iterations as we figure it all out.

The following functions are already in the Object category, but were repeated inside the executable. Is there a particular object that allows only those functions?

The following function was alone inside the executable. I would associate it to Object and/or Player, but it should be tested.
