My thinking stems from the card game hearts or black mariah, where to have a little is detrimental but to "shoot the moon" is beneficial

There are four city tiles with only a quarter of a unique pennant on them and to have one or more in your city when you complete with majority results in you recieving the corresponding token into your supply.

for each such token in supply at game end penalises you 10 points, but if you end the game with all four, rewards you 40 points instead

Ive had a rethink on the points, I think that as you can see when someone is trying to shoot the moon, the reward should be 150% of the penalty
 so -8 points penalty
and +48 points reward

i really like this... could something like this be adapted for existing resources in cities too?

That would work, at least as a test.
good idea

I think that the number of Tokens you need to collect to shoot the moon is the critical factor, too many and it would become near impossible. Too few too easy.

my first guess was 4, but I haven't playtested it but this way I could.

When I think cursed pennant I would think a pennant I'd play on an opponent's city which would deduct points

it is

I've play-tested this once and I think its hard enough to "shoot the moon" (lift the curse) that most of the time it is as you would think. but there is the possibility that they could turn the tables and profit from your efforts.
