I have nobody to playtest with, so that route's out, as is any likelihood of these actually seeing play, but I do like making content for things, so I'm tossing around ideas for an Umineko-related fan expansion, based largely around a theme of draconian measures, as demonstrated here.
Witch's Epithet ($7 Action)- Trash your hand. Gain a Gold for every card trashed.
I couldn't decide between $6 or $7 for this. I settled on $7, as it makes it more of a late game card. I figure the only cards you reeeeally are gonna have to think about sacrificing are Provinces, so making it $7 makes it that much more a late game buy.
Golden Witch ($4 Action)- Your choice: Either everybody else gains a Gold and a Curse, or you do.
I am honestly not sure whether the effect is beneficial, but it'd be solid in the presence of other cursers to drain the pile.
