You'll rather want black fairies if you want to use the armors on Nanaly.

Yeah, when I said that, I meant "black" but wrote platinum (because I was talking about platinum armours). I'm actually at 7 platinum fairies, 4 black fairies, and one rainbow fairy. Haven't quite figured out what to do with the rainbow fairy yet. It doesn't seem to work in place of other fairies for CC'ing purposes at least (my initial thought was that it could be used in place of any other fairy, but apparently not).
Gold / silver fairies fluctuate a lot because I get so many of them that I just combine them with the copper mage from Dragon Hunting every time I hit 4 of either to give one of my golds or silvers a good bump up (and leave one behind for use in CC'ing if needed).
Rainbow fairies increase skill levels with a much higher chance than using fodder with the same skill. And they can only be used by themselves. Save them for now.
Agreed on saving. Best used when you want the last 1-2 skill points to hit 5/5, unless it is a very rare unit that you barely ever get. Got one as well and have no bloody idea what i'll use it on in the future.
