Hello tourist faction buddy! :)
Wow this is so good! Having gone with this theme myself, I can appreciate how well designed your sightseers are. I love the redo of the retinue/decree aesthetics as a travel itinerary, but combining it with its own deck is a fresh twist that makes for a really cool mechanism.
Then there are so many little things that just fit naturally with the theme and the lore, like weaker battles if there are no visitor centers, hiring of local guides in the form of the clearings' inhabitants by spending cards, the Loyalty Program, collecting Souvenirs... it's all so well thought out!
Extra points for the art, btw, they fit the theme and the faction super-well. My favourite is the top left guy on the faction board front with the flower on his hat, he looks way happy with his travel plans :)
All in all, very interesting ideas, another faction I'd love to try. Good job!
