For the second year in a row, the skin I bought RP and have been saving it for appeared in the list! (TPA Ori)
It was a hard choice between SG Janna and WW Lulu for the remainder of my RP, but I went with SG Janna.
Feels like the algorithm is spot on for one tricks like me. The skin i've been checking out the most for my main + several skins for champs I play on the rare occasion that I can't play her.
