Oh hey some travelling cards! There are things that I can appreciate here but I think there are many problems too.
Grand Witch: I'm starting here because it's the end destination and you kind of have to think about the travellers in the context of the whole line. I think this is very lacklustre, not just compared to Teacher and Champ but seeing all the cards in the line and how weak they are on a whole. With the cards in the line being overall very weak you'd expect some huge payoff at the end and I don't think this cuts it, even without the -6VP which means I have to gain 4 Victory cards before actually making any points off this I don't think this would be particularly exciting.
Another thing that makes no sense to me is that it seems like you made this a Curse type so that it enables the cards in the line that care about having Curses, but then it's a permanent Duration so if you play it you'll never see it again and it also doesn't actually interact with Mountain Hag, and you probably won't want to discard it to Witch Hunter, and it's very difficult to ever gain a copy of it so it doesn't work with itself... so yeah not sure what that's all about. I do like that being a non-supply card answers the question of whether you can gain a copy if an opponent plays a Witch, although I'm not sure if I can block Mountebank with this, or even discard it to Witch Hunter?
Orphan: A thing that comes with being a traveller is that people have to read 5 cards (6 in this case because of the state!) to understand what the card actually does instead of the usual 1. This means that you ideally want the cards to be as simple as possible and cut anything that isn't pulling its weight (this is true for any card imo but travellers especially). So like, why is this removing vp tokens? It only matters if you already have vp, probably from Grand Witch and Grand Witch is already giving -6vp for some reason so why is this doing that too? I don't think the cards need any of this -vp for balance reasons and it's just adding more clutter and confusion to them.
Witch Hunter: As is this doesn't really make Curses pay off or even mitigate Curses much in its current form because it's such a weak card by itself. Playing this and discarding a Curse leaves you at a net -1 card and +$2, +1 Buy up, and I guess you sift the Curse, but if you're adding the Curse yourself to enable this then that's kind of net-neutral. Given that by itself this is just 1 Pawn option and that Curses are Curses though it really isn't much of a payoff at all. I think this could totally just give +1 Card on top of what it already does and still be fine.
Think of the lengths Shepherd goes to to make Estates appealing cards, Pasture making the worth more vp for free and discarding any number of them for +2 Cards each! With this you have to go through the rigmarole of getting a Grand Witch for the extra vp from Curses, you have to go through Orphan to even get one of these and it can only discard 1 Curse. Oh and you don't start the game with 3 Curses in your deck for this to use.
Heretic: This could be a cool card, but I don't think it fits as a traveller. Okay so probably another long tangent, I think with travellers you want to find the sweet spot of a card that's worth doing, but wouldn't just be better as a regular kingdom card. A good example of this in the official travellers is Disciple, it's a really cool card, but it would be completely broken as a kingdom card because Discipling a Disciple would gain another Disciple... that's too many Disciples! Being a traveller fixes this as it can't gain copies of itself and it's also difficult to get many of them. Heretic on the other hand does 2 things that I think are problems for a traveller:
1. It introduces a State to the line, so now we have to parse 6 card-shaped-things to understand the line, on top of this Hunted is also a particularly difficult thing to understand, it took me 3 or 4 reads of Heretic and Hunted to actually get what they were doing, it's really confusing man!
2. Heretic has a completely different mechanism of exchanging than all the other travellers, which frankly I hate.
You also can only ever put tokens on Hunted once per game because you never lose Hunted so you can only take it once per game and you only put tokens on it if you take it, not sure if that's intentional?
Mountain Hag: Should say its pile, not it's pile. Minor grammar fixes aside, reading this I was expecting to see the big payoff for having Curses in your deck, Grand Witch sort of mitigates the -vp, Witch Hunter makes them slightly less bad, but we need a big payoff! And the big payoff for having Curses in your deck was... a Cursing attack? That doesn't make much sense here at all! The whole point of this traveller line was seemingly to make Curses desirable cards to have, so why would you want to send a Curse over to your opponent? Isn't that the opposite of what you want to be doing? Grand Witch is even worded as to give you vp if you gain a Curse, so it kind of counters this attack. I really don't get this, apart from that it would be weird to have a Witch that doesn't give out Curses.
Some final words on the powerlevel of these...
- Orphan is Abandoned Mine with a drawback.
- Witch Hunter is worse than Pawn unless you line it up with Curse.
- Heretic is Page that you have to pay $3 for if you want to exchange it right away.
- Mountain Hag's +3 Coffers probably would be fine as a regular $5 and the Cursing makes no sense given the context of the traveller line.
- Grand Witch represents a fairly modest amount of vp given the -6. I can see that this is trying to be more of a late-game thing than Champ or Teacher so you wouldn't rush out of the gate for Orphan or exchange Heretic as fast as possible but really there are way too many drawbacks here for what the end reward is.
Sorry if this was too harsh, I think these still need a lot of work before they're up to the best standard and I just want to help.
