Scott I have so accumulated dupe Eddies much like your roster. One sharded and one not of each one almost. After AAA they are useless. Clearing AAA requires 5 Eddies and 15 allies of each class worthy of winning. Losing 1 or 2 of these five is not likely, but would force you to have 6 or 7 Eddies of each class as insurance. One of each Eddie maxed and sharded should suffice to get past any hurdle up to clearing AAA, so having dupe Eddies doesn't make sense. I have decided to retain one of each and build up the roster of allies instead of hoarding multiple 5star Eddies.
