this looks like quite a poor board for SP here. No cheap cantrips. All the key cards are at $5, which is hard to reach while building up your SP's. I think if I wanted SP here, I'd open silver/silver here to try and get a counterfeit ASAP, which helps with buying power and thinning. OTOH, the engineer wants a margrave early to slow the money player.
It looks to me like some kind of bandit camp/margrave/counterfeit thing ought to be quite strong here, tho. I've solitaired it several times and i get a megaturn around T20, which seems absurdly slow, but I can't figure out how to make it faster.
