这些东西在原厂标签叫做 Retired skins 早在2011年就开始逐渐淘汰
程如大家所知，Riot对自己呈现给玩家的产品很龟毛（这跟玩家认知有落差我知道）
不管是英雄还是造型，隔一阵子就要检讨、重制
而这些大多都是古老的造型，早就不符合Riot的现今的美术品管
所以下架不卖了
根据Wiki的说法：
Retired Skins are skins that were normally available in the League of Legends
Store, but have been deemed to be the classical skins of the game and are no
longer top quality skins. They were chosen by Riot to be placed in a Sale
(75% off), after which they would no longer be purchasable in the store to
make room for the next generation of champion skins. They were all put in the
Legacy Vault to make temporary appearances on special occasions.
退役造型是指那些通常可在商店买到，但被认为跟经典造型太过相似，而不再是顶尖品质
的的造型们。Riot选择将这些退役造型以 2.5折的优惠贩售后下架，腾出更多空间给新世
代的造型。它们都有机会在特殊活动中以限时贩售的方式出现在商店。
好的，所以从以上内容我们知道了几件事
1.原厂认为不该再贩售的低品质垃圾（如：魔幻卡牌）在台服持续贩（ㄌㄧㄢˋ）
售（ㄘㄞˊ），最久的长达五年。
2.说好的2.5折下架前优惠呢？
