I see an issue as a tabletop player: it does not track the amount of trashing, so people will forget and lie about how much they can trash when playing physical dominion.
That's no worse than Treasure Hunter or Smugglers, really.
Yeah, but those have to work that way, this one really doesn't. This could just trigger at the end of cleanup. Then it wouldn't be a duration and wouldn't get stuck in play which would nudge its power up, which is the direction I think it needs to go, I think it's a little on the weak side.
You're probably right. This card went through several versions, and the duration part was left over from an earlier idea about a kind of "retroactive moat" that I couldn't find a good balance for. So, the idea was you could trash a curse that another player had given you right away, among other things, but it was way too complicated, and its power level was very much dependent on what other attacks (if any) existed. After I abandoned that idea, I kinda overlooked the fact that the duration effect no longer made sense
