Waiting for the Trade X-Factor: Scar Tissue By Peter David, art by Valentine DeLandro and Emanuela Lupacchino Collects X-Factor 213-219   Why I Bought This: It guest stars the Black Cat who is perhaps my favorite Marvel character. It is also written by Peter David, who is one of the all-time great Spider-man writers and who wrote Felicia particularly well back in the day.   The Plot: The main arc is about an assassination attempt on J. Jonah Jameson. He hires both Black Cat and X-Factor for protection. There are also a few single issue character studies on some of the regular cast.   (spoilers below)
