It's been pretty much confirmed that the highest point value you can get for Fairgrounds (without Adventures) is 28 points.
The challenge: Find the fastest way to get at least one 28-point Fairgrounds in a solo game. Assume perfect shuffle luck.
The board must include:
Shelters
Colony/Platinum
Knights
Black Market (25 cards)
Either the board or the Black Market deck must include:
Fairgrounds
Tournament
Hermit
Urchin
Young Witch
At least one Potion-cost card
At least one Spoils-gaining card
At least one looter
If Hermit and/or Urchin is in the Black Market deck, Graverobber and/or Rogue must also be included.
Have at it! And no, I don't have my own solution... yet.
