Each fairgrounds is worth 7.
If you buy out the fairgrounds thats 7*8=56. Without black market
You've forgot the "other Madman".
what other madaman?
The other upgrade-y card.
Now, to get all this, you'd need in your kingdom:
1)Fairgrounds
2)Young Witch
3)Tournament
4)Looter
5)Spoils-er
6)Hermit
7)Other upgrader
8)Potion card
And the wherewithal to get all of those, the two other kingdom cards, the Bane, all 5 prizes, a Spoils, a Madman and the other upgrade in your deck all at the same time as the game ends. Oh, and keep all your Shelters and at least one Copper, buy an Estate, Duchy, Province, Colony, Silver, Gold and Platinum.
I think I'll just go BM->Provinces.
