My first purchase was also the day I started UR, Oct. 6, 2007. I bought Otome for 149 clintz and for the life of me can't remember why. I had no Fang Pi Clang cards in my first deck. A few days later I bought Windy Mor for 270.
I, like Puppychow, started buying Junkz early on but also Rescue, who were released shortly after I joined. I only payed around 3000 for Marco and a little over 1000 for Alec.
