Dark Dealings - $5
Night
Each other player may gain a Curse to gain a copy of a card you have in play. For each card gained this way, you may gain a copy as well.
If you don't gain anything, gain a Gold onto your deck.
Things of note
1: The person playing Dark Dealings can technically gain a Curse and a copy of whatever another player gains through it. There may be cases where this is desirable, like with a Trader in hand.
2: Even if other players gain cards off of it, you can still opt to not gain a copy of anything to get the Gold onto your deck.
3: All other players choose to gain a Curse and a card before the player of Dark Dealings chooses to gain anything.
4: Other players make their choices starting with the player to the left of the active player and go clockwise.
5: If the Curses are gone nobody else can gain anything off Dark Dealings, but you can still get the Gold onto your deck.
6: This is not actually an attack as everything is optional.
A weird gainer that relies on others to get multiple cards in a turn. While a non-terminal Gold gainer/top-decker may be underpriced at $5, the possible benefits to other players makes this reasonable IMO. Feedback is welcome.
For example, in 4-player games, when only DD is in play and all other 3 players choose to gain a Curse and a DD, 6 cards are gained. So, I can gain a Curse and a DD 6 times, right?
