Apothecary, Baron, Chapel, Conspirator, Contraband, Library, Lookout, Native Village, Potion, Royal Seal, and Scrying Pool
Chapel is go-to - especially with Conspirators. But maybe Lookout is better as it's +1 Action? Or wait. There's Apothecary, so maybe you want to hold on to your coppers. So Chapel it is. But wait, your +buy is Baron, so maybe you want to keep your Estates? But Scrying Pool+Conspirator doesn't want the Estates or the Coppers. Hm... In any case I'm going to want to build an engine, so I might want more then one terminal buy. Contraband could work there, but it doesn't fit with either Apothecary or Scrying Pool. Maybe play multiple Barons? But then I need actions. Only actions are Native Village. And it works great for tucking things away with Apothecary. I guess that could work. Wait. Library? That works great with Native Village. It could even work with Conspirators. But not with Apothecary or Scrying Pool.
Hold on. Maybe it's some weird combination of all that? Is there a synergy I'm not seeing.
OK. I'll go Apothecary to pick up coppers, Scrying Pool to draw the actions Apothecary lines up, Conspirator to get extra cash (and get picked up by the Pools), Baron for extra buys, Native Village for the extra actions. Maybe a single Contraband (since he won't know what I'm picking up on any given turn - so many options).
OK. I'm set.
Now what do I open with? Baron? Potion? And what about my $3? Lookout? Chapel? Silver? Copper?
Really interesting game:

I invested a little more in the engine with extra buys and ignoring Province until my second last turn - and it paid out. P1 advantage helped, but I don't think he could have got a province on his next turn anyway)
Fun one. If the Kingdom challenge was still open I would have submitted this baby for sure.
