the same way people get all of their legacy skins... They wait for them to go on sale and buy them.

{quoted}

How did people get it? And will it ever come out again?

Won't lie, I really want that skin haha. I've been waiting a complete year to buy it almost.. Last year I was 30 minutes late on buying it, I was so sad. Call me weird but when I'm sad I usually play Amumu lol, feels like the right moment.

Start of the season (2015). Should return in late January to early February of 2016.

It should come out when Season 6 starts for a short duration.
