I don't know where you could find the cards; i would say check ebay, craigslist, or amazon, but there is a list of all the cards on the .hack wikia. The link is: http://dothack.wikia.com/wiki/List_of_ENEMY_Cards
Most of the maps I built took anywhere from 1 full day to about 3 full days to build. Larger maps like the root towns take longer. Its going to take us a while to completely retexture Mac Anu with microblock designs.
I finally decided to join you all.. I probably should have done this a long time ago lol. I was the guy that started The World R:Craft with AzureZhen, and I am currently one of the map makers on the server.
Nice to meet you guys!
