Scourge Illusionist bug

Scourge Illusionist
“Deathrattle: Add 4/4 copy of another minion in your deck to your hand it cost 4 less”.

This card is not just pulling Deathrattle minion, but it also pulls out Kingsbane which is a weapon!

Are you sure he didn’t play Sketchy information and pull kingsbane instead?

Yes I am 100% sure of it!
