As economy engines go the loan shark isn't the best. Although she doesn't require 2 link like Underworld Contact or 2 free MU like Data Folding having a card that only works when you have between 0 and 5 credits at the start of your turn isn't great. And she's unique so you can get best get 1 credit from her per turn.
Oh, and should you actually get to 0 you get smacked around by her collection agents.
Not all that appealing.
Hang on, wasn't there some card that you want to take meat damage for? Clan Vengeance or something? It does work to get some counters onto Clan Vengeance, but it's still not a great deal. For taking 3 damage you get the ability to trash 1 card at random from HQ. Well, I guess it could work if you can get the corp agenda flooded and Jackson is out of the picture. And unlike most other sources of damage you can actually control this one.
I'm kinda surprised this isn't an anarch card since it fits well with the anarch theme of damaging themselves to gain power. But maybe FFG made it neutral because of its lower general power level.
Tip: I've Had Worse is good to have in your hand when Dadiana fires.
