I saw that silvererne posted this same question on the forum on Mon Jan 30, 2012 4:33 pm, and even though the thread shows it has had 52126 views, there have been no replies.
I have the same issue with OverPower as silvererne has, having a LOT of cards for this game, and no scans for helping determine which card I have.
So, I ask, is it possible to make scans of the cards, use the Add Card List from File feature in the Cards You Have section, generate the template, save and import to Word and add the scans into the document and then upload it? Will that add the scans to the server for other users? It is really frustrating that there are little to no scans for this game. It has been very difficult for me to figure out what cards I have.
