Well, that solves that problem!
Do you want your friends to hate you? Because this is how you get your friends to hate you. A curser that junks curses, coppers and has an anti-self-synergy? Horrible. I mean, Dusk Villages are going to great slog games if there is no trashing. You know what sucks in a slog game? Cantrips that do nothing for you. At least regular ol' witch gives you +2 cards and mountebank is worthy a silver.
The only redeeming feature is that you get the curse and copper in your hand, so it doesn't immediately at to the onslaught that is your discard/deck (except if the other one plays a militia, than he is just a completely awful person). I mean, the copper in your hand is definitely necessary to gain some kind of purchasing power in the game. The curse is, well, like in any other game. But man, if you can survice the onslaught of curses and coppers and you can still play Dusk Villages, well, the opponent can even draw another card. So how many of these do you want? Well, it junks better than witch if you can play two in a row, but if you only have dusk villages than the amount of cards you are getting extra is zero. So what to do?
I was even thinking about giving this card the set up that you should at the Plan event to the supply. That would be cool. But it is how it is.
Either way, we have had lots of fun with it. But I can't find anyone to try it in a game with no-trashing. I wonder why. (But I don't think it's anymore sloggy than other cursers such as mountebank, cultist or regular witch.)
