With necro, even if Advisor and Forager weren't there, it would be possible to get 5 Goons in play, but no more. I wonder if it's possible to design a kingdom where it's possible to get x Goons in play, but not x+1, for x>5 (and obv. x not equal to 10). Oh yeah, Crossroads should help for x=7. Is it possible for x=8 or 9? Oh, you could just use Dame Molly. So Procession+Molly gives you 4 actions, Procession+Necro makes it 7, then Procession+Bailey makes it 8, Tactician to get 9, and just don't include Crossroads. I thought I was going to make a cool puzzle out of that but I guess I already solved it...
Actually wait, you can start with Pr>Pr>Pr>Molly,Necro,Bailey, and now you're at 10, so knights don't help, because as long as Procession and knights are in the kingdom you can get 10. Wait what if you throw out necro, just use Pr>Pr>Pr>Molly,Bailey,Crossroads gets you to 8, then Tactician to get to 9. So I think you just have to not have Necropolis. Okay, I think I did it now.
