My method is pretty easy , just go to the Driftveil Drawbridge and if you see little shadows that either means there's a wing or Pokemon there. If you got a wing you can either use it on any of u Pokemon or sell it for I think 1,500 you can get these wings anytime u want it will happen all day. :P
It relates to the ghost in pokemon white 2/black 2 where she haunts the strange house and in it is the lunar wing and then cresselia will appear on Marvelous bridge if you have the lunar wing.
Yes, go to marvelous bridge (you can't go there until you beat the main story) and then stand in a circular shadow, they pop up now and then. Each time you do you will get some kind of wing.
You get Silver wing After defeating the team rocket in the radio tower POKEMON SILVER ONLY. Rainbow wing Is found much later in the game After the Elite four In pewter City POKEMON SILVER ONLY.
Those items aren't in LeafGreen.
