So I'm looking at this board and thinking, no +buy, no virtual money, no +action, no trashing, SP is out. That leaves apothecary/beggar, but that probably needs +buy too. Big Money it is. Plus, I'm playing against Stef, so I probably can't beat him at engine building anyway (note that this is a terrible reason not to go engine).
However, there is pseudo+buy in horn and outpost, and scheme really really helps the outpost. And there is trashing in
transmute which is really a key card in this engine. Stef never buys/gains a treasure besides the potion and the Horns, so without the golds from transmuting estates, he'd never get to $8. Later, he uses the transmute on a scheme at the end for a duchy, which gives him the win that turn. (If that hadn't been enough right at that point, he had an outpost in hand whereas I could only buy an estate on my next turn, leaving up to 4 effective turns he'd have had to make up the difference.)
Thanks to some decent luck (his spying attacks never really hurt me - the one time he skips a journeyman i'd have drawn it dead anyway), I get four provinces by T12, but it's not enough. He gets the horns up to 8, cashes out, and wins by a
nosetransmute. "Such a powerful card," he says.
PS: Stef said he hadn't even noticed the possibility of Journeyman/BM. I guess when you set your sights high...
