Monster Cards?

So I was wondering what the reason is that monster cards don't work, I used to really like collecting them so it would make me super happy if they worked on this server.
There is a monster book hotkey in the key config.
So if it's possible it would be awesome to be able to collect monster cards again.

Edit: I've looked through the forums a little bit and I could only find really old posts, so I don't know if anything has changed.

 

Still no monster cards. I remember doing this in the old maple, was quite fun to collect them all.

 

I believe they will be added in the new source.

 

Ah, that would be awesome!
Thanks

 

Monster book will be in the new source, the monster cards you're talking about are for making match cards.
