Okay I f***ing love this setup. Check this out, helpfully divided by costs:
11 - Colony
9 - Platinum
8 - Province
7 - King's Court
6 - Hoard
6 - Gold
5 - Minion
5 - Duchy
4 - Ironworks
4 - Worker's Village
4 - Potion
3 - Swindler
3 - Watchtower
3 - Silver
2 - Pearl Diver
2 - Secret Chamber
2 - Estate
P - Vineyard
0 - Copper
0 - Curse
First turn, my opponent buys a Swindler.
L O F***ING L
I destroyed him after buying a Watchtower and using his Swindlers to rid myself of all my Estates, most of my Coppers, and even one of the Curses he gave me, and even when he Swindled my Gold into Gold (why he didn't give me Hoards instead is beyond me) I was just able to put it back on the top of the deck like nothing happened (instead of it getting discarded). And the only useful switcheroo he could even make with the Swindler was Minion to Duchy, which he pulled off only one and I trashed the Duchy anyway.
Worst time to play Swindler EVER. Watchtower owns.
He also used Ironworks to buy out all the Worker's Villages which was a completely inane play, Worker's Village serves very little purpose here and 10 of them in your deck serves none at all. I didn't buy any either of the 4 costs so he wasn't able to swindle any Potions onto me.
