I hope this helps I have copied and pasted here 2 of the factions mandalorians and seperatist and all their pieces under what set, starter, map pack, etc and their numbers in that set. This is from my personal log. All you have to do is highlight and paste onto a blank word or spread sheet. I will do other factions in the next couple posts and you will have all of them.
