Cupid Zac skin idea
After the rework, it appears that Zac is the true matchmaker in Runeterra, bringing enemies together through his Q and his R. This matchmaker extraordinaire really needs a skin to accentuate that tendency so I suggest a Cupid Zac skin. When Zac slams 2 people together, it could make a kissing sound and have hearts pop up or something. I'm sure Riot could think of lots of fun things to do with this skin.
