Flarefang SD's effect should be active only while he's on the field. After finishing resolve Heavens Sunshine, call Balle Soleil by using Flarefang SD as a cost, he's not on the field anymore. So I don't think that you can draw by Flaredfang SD's effect.

Someone who know the similar case please confirm it. Because I'm not sure too.
