On the first two:
Use the constraint "!platinum, colony". Vice versa platinum will not show even though you required it.
Nice! Hadn't thought of this, but I did say
'generate a Kingdom', not 'generate a supply', so technically my solution is still unique ^^#3: Anything where the excluded set matches one of the 'common' Kingdom cards; you still play with Duchies even if you ask for no $5 cards, or no Victory cards, and so forth.
Ha, yes, but that's not quite what I meant. As the Isotropic constraint interface does, I used 'set' to mean 'set of Kingdom cards' (e.g. Seaside, Base). Maybe I should have just said 'How can you get it to generate one with a card from Seaside when you've constrained it to 'from 0 to 0 cards with set=Seaside'?
- How many ways are there to stall a game indefinitely without your opponent being able to end the game or force you to resign? Is it possible to force this to happen without any complicity from your opponent?
I think the KC-Goons-Masquerade pin (and anything else with the same basic idea) will do this. There are probably others; I'm not sure.
Repeatedly revealing a reaction card should work too. Though I suppose you could consider your opponent "complicit" in this plan since they have to play at least one attack ;P
These are the two I know about, yeah, along with the similar Bureaucrat and Cutpurse strategies discussed in Young Nick's recent thread. The Masquerade version is the one I meant to single out with 'without any complicity', since it doesn't depend on the contents of your opponent's deck at all. This isn't a very precise definition since they could always stop you from doing it with Saboteur or Swindler, or by winning the game. But it feels different from the others, which specifically require them to buy/play/draw/trash certain cards.
