DragonBlade Riven

On the 1st of Janurary, I joined LoL and I have mained Riven for most of that time. I have the skins available at the moment but I would really like to get Dragonblade Riven. Despite what I have heard from my friends that do own the skin, I think it looks really nice and, in my opinion, is better than Battle bunny Riven which is saying something! I have accepted the sad fact that I won't be able to get Championship Riven because that was the season 3 prize for being in gold division or higher(I think!) but I was just wondering whether I will ever be able to get the skin again.

Quick Edit: I just read a reddit post by @Hippalus http://www.reddit.com/r/leagueoflegends/comments/1ol53y/the_harrowing_approaches/cct1cnx He says that the next Lunar reveal skins will be Leagcy. From what I know, legacy skins are sort of limited edition but they come back out. I don't know if this means I will be able to get it next lunar reveal(if it is a reoccurring thing-as I say, I have only been playing league since the start of the year 1.1.14 to be precise! ;) ) or if I will be able to get during the sugar rush thing happening at the end of this august- http://na.leagueoflegends.com/en/news/store/sales/satisfy-your-sweet-tooth-sugar-rush Thk you again for reading this post. I appreciate it- I did say it was a quick edit but I guess I wasn't very quick so thks for helping the noob. HUGS AND SMOOCHES FOR YOU- if you can answer my question that is...
