These thoughts from an ETF perspective.
Corporate Shuffle is two influence and seems pretty click intensive, but it does come in a pack with NAPD Contract and Quandry, so it gets access to other good cards.
Disposable HQ is one influence, which is good, and for my ETF deck gets me Advanced Assembly Lines and maybe Corporate Sales Team.
Special Report is two influence and (like Shuffle) you might end up drawing more agendas right back into your hand -- if you are using it to try to manage the location of your agendas.
Alexa - two influence -- might be most promising, although certainly limited in important ways, as one of my 188.8.131.52 ETF decks already uses this datapack.
Preemptive Action -- Zero influence great, but it is the only card in this pack that I would want to play, meaning I might as well use my 1 card on Jackson.
Thanks for the ideas. It feels to me like I need to figure out some play style changes to go along with hunting up some substitutes if I want to figure out how to play in a world without Jackson.
