I can’t help but notice you’re not playing Cache. I think if you’re running Pawnshop it’s a click for 5 credits (next turn). I guess you might have MU issues, so they become a dead draw later.
I don’t get Rex in a deck that’s running Gordian Blade, even if you get the install cost back, it’s a pretty long winded way to maybe gain a couple of creds.
I’m not sure if it will work, but -2 aesops, -1 Kati/Johnny M, +2 hostage, +1 Medium would be something I’d consider. I think Aesop’s is efficient enough that using a hostage for him is worth it. Early Medium really upsets NEH, Early Medium upsets a lot of folk.
You’d also have 1 inf to spare for Feedback Filter if the PE matchup is making you sad.
Zona Sul Shipping would be mediocre at best, even without the trash if you’re tagged clause. Put it back in the binder
