I think you have the wrong link in your post; it leads to a game that doesn't include Torturer.
I was your opponent in that game. The ruins definitely slowed down my engine, but the biggest factor (from what I could see) wasn't Cultist; it was Scheme+Moat. I didn't buy any Moats, while you bought several, and used them quite effectively. There were two turns where I played 3 or more Torturers in one turn, but you blocked them all with Moat. You then played Shanty Town, some Schemes, and the Moat and returned the Moat to your next hand. I didn't see the potential there until you had already bought several Moats and Schemes to add to your engine. I actually ended up taking more curses than you did, because I didn't have any Moats and you did.
If I am remembering correctly, there was only one turn in that game where you played two Cultists. I don't know how effective the Cultists would have been without the Scheme-Moat interaction.
