Implement a "mystery gift" option for yourself - similar to MapleStory's Gachapon

So the mystery gift feature reminded me of the game MapleStory's Gachapon - basically, Maple also has currency that is exclusive to real-world currency. You buy a ticket in game, and then you can go to a "vending machine" that gives you a random item that could either be worth a lot or worth very little. I think this would be a cool feature to have, as maybe sometimes you want to gamble on getting on getting a skin you want. I don't know if this would include legendary skins, but perhaps Riot could work on potential price costs for different levels of skins, or just have one overall price like they do for the mystery gifting.
