Targetted Eddies

Is there a way to target specific Eddies to add to the collection? I consider myself somewhat lucky as in about 16 months of playing, I have obtained some of what seem to be fairly rare Eddies, along with many repeats of ones I already have (I think I am at something like 90 sacrificed Eddies now). However, I am still not able to have claimed Samurai, Shaman or Doomsday Eddie. There are a few others missing, but these are the ones I really want now if for nothing more then to see there special attacks.
On that note, I purchased Eternity Eddie with FC a long while back and am closing in on Alexander Eddie, however, Angel or Gambler looks awesome as well. Is there a clear winner in those 3?

You need all three but i would focus on gambler first

Yes. Get Gambler first, then I'd go after Alex
