Collectible Card Game Headquarters

Hi all,

going on into my crusade for customization, I've seen that I have some "unused" slots which go from 901 to 908, plus a data card (slot 909), that is marked as

"This card holds data for the attached card and is not important for player use". Also slot 31 is marked as "empty" but not as "none"

I would like to know if those slots are really unused, since they can be replaced and don't start with "--".
Also, Jatill, is it really impossile to remove Necropolis of Azar, Spawn of Azar and Orcish catapult? They are so lame!

When I replaced those slots, the game stopped to work!

Well, then. It looks like that the CSV is not used but the magic.exe is!
Instead, I know for sure that the slot 1999 is free and can be used but Jatill's editor doesn't reach it so a manual change must be adopted.
