I really think we should keep 'unofficial' stuff separated from the WoTC stuff.
Having an 'Unofficial' folder in which to put 'Rugrats' and such should be a great way to handle the database. I really don't likee seeing 'manga arts' or 'weird looking card' (different from MTG layout I mean) mixed with promo cards and unreleased rare stuff.
Separating things means we could also manage fake cards.
Two sets comes into mind right now: Gauntlet and Monty Python.
Using subfolders into the 'unofficial' category could give the chance to archive for good 'all things Magic'.
What do you think about that?
