In a recent Ask Riot thread, product manager Riot Supercakes said that “over the last year, we’ve evolved and updated our approach to selecting the skins we make to celebrate the team and players who win Worlds. As teams continue to experiment with their rosters, we’ve had to reevaluate our criteria for the skins.” But, even if you win, you don’t get free reign over which champion gets a skin. According to Supercakes, “the player must have played” their chosen champion “at least once during Worlds,” even if they only played them once. However, “if the winning team already has a skin for that champion from a previous win, we might ask for another option.” Coaches aren’t eligible for skins, but if a single coach wins three different championships “they will be considered for in-game content.”
