Not the actual base this time (like with UD) but when I started purging other PC things, I wanted to keep up the trend of getting all of the Sens FWA (only those who start as a Sen).   I also couldn't part with the Sign of the Times cards I had in my player PC's, so I added those to the mix as something I like to get.  Should give me a nice assortment of Sens autos through the years.
