I can't seem to find this anywhere, so I am asking reddit. What is the most % off a skin can be, and if you do not know, what is the most % a skin has been on sale for you?

Please stop lurking and entry, the amount of times even in plat 3 that i see duelists lurking is insane, its pretty much always a 4v5 cus they alwasys remain last after not doing anything the entire round
