Onimarus1 votesIt's been in the game before. If I had to recall when, I'd say during the Black Market event.
King of Mongoose1 votesi know but this is the only one that's back into the live servers database
It Is I Emoto1 votesmaybe they just forgot to remove it?
VaporeonKun1 votesIt's been sitting there for awhile now. It either is being thought out for potential use or it really was just forgotten when removed.
It's also possible there might be code attached to it that might be preventing them from removing it right now. <-- This is just a hypothetical situation
AMYS GRAVE1 votesThat and Dead Mans Plate which was also a BMB item.
TheProAndrew1 votesin black market that item gave 20% cdr also ;D in game
Jbels1 votesThis item would be cool for roaming supports
kaltenashes1 votesthey could add the item 'mirage' (or something like that, its from bmb) in aram, the one that makes you have the same look as your ally
Nekusen1 votesit was oddly never removed from the item set list, nor removed from the forums icon 
but riot said there were never plans to add it to the game.
Ralanr1 votesMirage blade is still in there as well. No idea why.
