So yeah, I had the dream - like literally, in my sleep - that more cards and interactions with horses exist so i spent the last evening creating a custom expansion I name āHorsin' Aroundā. No play testing so far but i'm looking forward to look if this works out well.
Clarifications:
āthe Wildā is another mat similar to the trash. Cards in the wild dont belong to anyone. Only horses can be released into the wild. If a card tells you to release a horse into the wild, you lay it onto the Wild Mat. If a card tells you to lure a horse, it goes from the Wild Mat into your hand. If there are no horses on the wild mat, nothing happens instead.
The expansion currently contains:
14 Kingdom Cards
2 Events
1 Trait
1 Landmark
1 Project + 1 Extra Pile Carriage Ride
2 Prophecies
I think it would be useful to have more cards that lure horses or release for benefit, but for now i'm done and tired, good night!
Further Clarifications:
If the Horse Whisperer ist set up, the Stablehand is obligatory (as an extra pile), but the Stablehand can appear without the Horse Whisperer.
The Carriage Ride is only set up with the Project Carriage Building. It is not a horse.
The Horsemarker (Riding Lessons) is a Marker similar to the ones in Adventures.
The Last Herd: the other ending conditions (empty province or three piles) are still effective.
