I've been trying to find a strategy that has Jack in it that beats double Jack.
One idea I had was something like Lookout (to kill coppers) + Festival (disappearing money).
It likely won't work (Jack+Festival doesn't), but I figured it was worth a try. Unfortunately the simulation has Lookout kill Estates instead of Coppers.
I've never tried to change the rules on how a card operates. Is there a primer somewhere to help with that? I imagine, as far as changes go, this would be a very easy change to make.
