Unusual taunts died october 21, 2016 with scream fortress 2016. In the update a new item was added, unusualifiers. If you dont know these are items that you can apply to taunts to make them get a random unusual effect. Problem is that the chanches to get a unusualifer were so high at the time that you could get like one or two every ten boxes, i'm not joking. Because of that many, and i say many people started getting unusual taunts. Some unusuals that were worth even 800 keys dropped to >100 keys. Today the chanches of unboxing unusualifiers are exactly like the chanches of getting unusuals, 1.00%. While i'm at it i'll also tell you the chanches to get an aussie 3/4%
