This was due to the extremely annoying niche and gimmick that Trickster has access to and the possibility of it's very high dps shouldn't exist. It's due for a nerf atm, but for now, it's staying banned in Elimination as setting up F's are too good and do very well in transition to FS.

-30 dmg from 1 direct knife party during F. Knife party fires 2 knives so theoretically you can do 60.
-Bleed is incredibly good and gives free tick residual damage which stacks very well, making it a very good beat among the likes of defender, guardian, most brawlers and etc.
-One of the fastest stealths in the current game, objectively better than stalker's
-Knife party + stealth can also do immeasurable damage.

Not banned in 1v1 because doing the latter actually doesn't require a ban since it isn't terribly braindead and the gimmick abuse isn't very easy to trigger [especially since baiting is harder], but nevertheless, this will be unbanned if the nerf is good enough.
