Ok, so I'm still wrapping my head around Travellers, but I'm having a hard time seeing the benefit of going all the way to Teacher here. Pretty clearly you were doing the right thing going for KC, Fortress, Poor House, and Doctor. (Maybe I would have added an Embassy to help increase handsize, too.) If you go for the Peasant line at all, it seems like stopping at Disciple is better and then using a Peasant or two directly for the buy. Going all the way to Teacher just to put a plus buy token down seems slow in this kingdom.
