Why was ravenborn leblanc put int he vault but we never lost haunted zyra

Also of the two Zyra's seems much more holiday related.

because leblanc is an amazing champ and deserves to give its veterans something to cherish before riot whores her out for money later.

that makes no sense. she only has 2 very low quality skins. I used to like prestigious but now with the rift changes im losing track of her everytime i use my distortion
