Lets take a normal turn 2 game situation. Youko has to walk once then can Blackmail twice. First she hits you with Backroom Dealings and forces 2 card discard. Now you have 3 cards in hand. They're probably quite dear to you, so you will not discard them for Blackmail. What does Youko get? 4 (!) pass tokens, which means total activation control, and some spares for leverage if you want, and 2 actions where your beaters probably charge backwards out of position and hit your own models.
If you're taking models with no potentially dangerous bonus actions, isn't that already a form of control? I mean it seems like a lot of what Youko does happens before the game starts. No double-edged bonuses. 5 card hands. Either have to plan to score schemes late or give up activation control starting on turn 3.
I will say, it feels like her crew could use a model with Hostile Work Environment, or something that prevents a 2 SS Bayou Gremlin from undoing a master AP with an assist.
