New Project Skins

So as most of you know they released a teaser for a line of 5 new Project Skins to go along with Project: Yasuo

Trace 1: The trace is lost so do you guys think it's new champ, a hint at a champion with a "lost" history, or maybe just its building suspense?

Trace 2: I think this one will be Leona. Anyone think otherwise?

Trace 3: The purifier is most definitely Lucian so this probably relates to a Project: Lucian skin. You think I'm right?

Trace 4: This trace is Project: Yasuo

Trace 5: It's talking about marks and shadows, Zed anyone?

Trace 6: Lunging and Waltzing, is this Fiora or what?

Please leave your thoughts below if you think I'm right or not.
