Ok, I'll take a wild stab at this. I'll start with everything in the Fairy egg group, but I won't use all of them since even though there is a Dragon egg group not all of them are Dragon type either.
Cleffa line
Igglybuff line
Happiny line
Audino
Togepi line
Mawile
Manaphy/Phione
I decided against Snubbull and it's evo and although I was almost tempted to put Skitty and it's evo, I decided against it, too. Now for everything else I think could qualify.
Dunsparce (I don't know, it feels like it would go there)
Celebi
Chingling/Chimecho
Jirachi
Mesprit
Uxie
Azelf
Munna/Musharna (If you believe the Sandman to be a kind of fairy, I dunno. Dreams. It made sense to me)
Meloetta
Hmm...the butterfly pokemon. I'm not sure about that either, but I'm not going to include them. Fairy could be interpreted as targeting the mystical pokemon, but I am unsure on stuff like Psyduck/Golduck and the Lotad line, too. I guess I'll say the same for all other things based on a myth unless I otherwise say so. I won't tamper with Mew, either. Smoochum might, but I'm unsure on it. Also unsure on Buneary/Lopunny.
Maybe I'm not the right person for this, I can't decide what Fairy means and what traits it should have. This is just what immediately stuck out as feeling like it would fit.
