Note: When this was posted, the puzzle involved having only 1 card in hand due to double-torturer and and being KC-KC-KC-KC-Sab-Sab-Sab'd, which hit absolutely nothing in your deck. All 3 of these cards had to be in the kingdom, leaving space for only 7 others.
The hero's deck contains 7 Vineyards, 10 Cellars, 9 Chapels, 9 Moats, 9 Courtyards, 9 Pawns, 8 Secret Chambers, 8 (+3 starting) Estates, and any number of Coppers. He holds a Potion in his hand. He buys a Vineyard to end the game on piles (Vineyards, Cellars, Estates). He scores 54/3 x 8 = 18 x 8 = 144 for Vineyards. 11 for Estates. Grand total of 155 VP.
Obviously, I've just picked the first 7 $2-cost actions from the card lists on DominionStrategy.com. These could be any $2-cost actions.
Alternatively He's already got an arbitrary number of VP tokens from past Monument plays and so there is no limit to the solution
These solutions assume a 2 player game.
