Thank you for judging.
The goal with Fire Witch was to male a "Young-Old Witch" of sorts. I added the -1 VP to you for Fire Witch so that:
* If they trash Estate, it's basically Monument (they trash and gain junk, and you are net 1 VP compared to them)
* If they trash Copper, it's a Cutpurse AND a Swindler, so no overall VP disadvantage is balance.
* If they trash nothing, it's a Witch but without the VP disadvantage.
* Trashing Curses is ideal, but it's no VP advantage to do so (unlike Old Witch). Once the Curses run out, the Curser has a net 1 VP advantage, so in late game it could be a tough choice whether to trash the Curse or not.
So playing it doesntn in and of itself give you a VP disadvantage, though it will if the player you attacked has another way to trash Curses.
I was worried about it being too strong for $4 until I made those comparisons. Should I buff it ? I considered making tbe penalty for Curse trashing -3VP
