I redeemed it on the day I attended MSI (May 9th). All of my friends have received their skins, yet I still do not own SSW Thresh. I've checked every single day multiple times and I still do not own it. I've also submitted a ticket.
same thing is happening to me.... I received my TPA Ezreal skin, but still no sign of my SSW Thresh skin. I have no idea where it is and if I will get it. The only thing I could think of is they might be giving the skins out by each team. Example: First they give out all fnatic skins, then they give out TPA, then they give out SKT, then they give out all SSW Skins. I thought this until my friend got SSW Talon before I got Ezreal. The only other thing i can think of is they give it out by champion. Example: Corki, then Janna, then J4, then Karthus, so on and so forth. Bottom line is, I haven't got both of my skins and I want them. Riot will probably just be late getting them all out. Rest in pepperonis. 
for going to MSI
and Blazin, Idk. my friends got SSW Talon and Thresh. i should have thresh too
.> The guys who don't know about it really shouldn't be on this post. But, for every day you attended MSI, you got to pick one free championship team skin. (Fnatic, TPA, SKT, and SSW) I went on May 9th (SKT vs Fnatic; AHQ vs the team with ClearLove).
May 25th, still no SSW Thresh.
I received my codes at the event for the skins. Fnatic Janna, SSW Rengar, TPA Orianna, and SKT Zed.
