[2022] I've figured it out. The return of Graves' Cigar + This year's 'Championship Skin' theory.

Okay okay, stick with me here.

In 2014, Imagine Dragons performed at the World finals and we got a Championship Syvanna skin(y'know, that DRAGON champion). Could seem like a coincidence but in 2016 we get a similar trend where Zedd performs and we get the Championship ZED skin.

(EDIT: According to /u/x0hmychristian, "In 2015, Nicki Taylor sang Worlds Collide. In 2014 she was the lead vocals for Kalista's intro song. 2015 was championship Kalista", sorry I missed this one but yeah, Riot's all about those themed Championship Skins + Performers.)

Now, after years of neglecting Graves's Cigar, Riot randomly decides to bring it back up, coincidence? I think not.

We are getting Championship Graves with a performance by The ChainSmokers. Quote me on this one folks.

EDIT 4 Months later: Graves got a Victorious skin, not championship :(. Riot swindled me
