I was incredibly skeptical of this card.
To me it seems to say "draw more weaknesses and lose deck consistency" I am someone who is struggling to keep the other permanents out of my decks but this one I felt would never win my heart....until...

Playing bob you realize just how many good cards for him are either limit 1, unique, exceptional or just don't stack, reducing your deck to 25(or 28) doesn't seem like a lot but then you look at one other card he can take, short supply, after your opening hand you have 23 cards left in your deck, ten go straight to your discard pile, what are the odds you get items (for scavenging), improvised events or Weaknesses in there (a weakness you see in your discard pile is one you don't have to fear).
you lose 1 rogue slot, but you gain the ability to double the value of the other 4, so that feels like a win.
your deck consistency goes way up (scavenging, resourceful, scrounge, Lucky Cigarette case all benefit from this set up)
so anyone like me who couldn't see the value in this try it in bob with short supply, and don't think of the one game you end up seeing your signature in the discard pile, think of every game where you got to add 10 more clever tools to win the game with and not compromise your deck consistency to add them.
