There was one time when I had 3/4ths of the set complete. I've always had challenges trying to remain focused on a project long enough to complete it. There's so many cards in so many other sets that I really like and it was difficult for me to have several hundred tied up into each common and then anywhere from 4 to 15k tied up into each Hofer.
What's that? You don't believe I had 3/4ths of the set complete?? Oh, my fault, should have added that it was a Type 2 set I was going for....
