Still think one of the best fix would just be to remove the implied "zeal" on "fee" abilities. Give them one turn to be activable, like orders, and the automatic instant value that most SY cards can get after piling up coins can be countered.
With that in mind, 1 turn to activate, here's my humble opinion on fee cards and a couple others (and I apologize for writing a wall)
Igor: Leave him like that or give him zeal with a cooldown so he can either be removed, or not able to produce 3 copies in a single turn. I know, we don't see him that much but I think it's just because he's not been given the attention yet. Hard to compare it to other cards, like Adalia, since he only summons but still...
Sausage maker: he's fair, give him zeal
Helveed: zeal + reduce his profit to 2 or don't give him zeal. Again, a difficult comparison but Water of Brokylon is 11p for 8 points. Helveld is 10 provisions for 8 points. Ok, the dryads have harmony but Helveed synergizes with all the spawn engines and always gives more value.
Philippa could just detroy a card with power equal to coins. Like that she wouldn't be an instant win against decks relying on a couple key cards (and I know, that's the risk, but when seized you can use renew on it, and contrary to muzzle or the NG cards, you can't play around and can't steal it back. She's too strong). She'd be a mix of Cleaver and Geralt but as a faction specific card, still more polyvalent (not affected by shield, usable any time in a round)
Moreelse should be 10 provisions. 4 power, 4 damage, like Ifrit and Regis, but with tribute as add-up to faction specific. Why 9 here?
Doadrick: I love him but he should have a cooldown of 2. Being able to switch a card/turn is incredibly strong and has somehow gone under-exploited until now
The Borsodis: without zeal, they'd be ok. Just imagine Johnny and Sarah with zeal. They would be strong... Other comparison with unicorn/chironex. U/C give you 7 point with the first, then 10 with the second IF the first is still in play. Borsodis bros: 6 and 8 points, but you don't need to have one alive to have the other's benefit AND they are both 1 provision less AND they also give added value over time as engines.
Kalkstein is an amazing card and I don't think it needs to be nerved, but compare it to Ceallach. 2 more power and you can use him anytime later on. Ceallach purifies more than one, yes, but how often is it used? He's a spring equinox with 3 power that can't purify ennemies! Either remove Kalkstein's zeal (which I don't think is needed) or buff Ceallach somehow
The 6 provisions cards are really good and imo pretty balanced. Love the tunnel drill which would need zeal.
Endrega, blacksmith naturalist, executionner, sea jackal, seductress, eternal fire disciple: I'm not gonna re-compare them to other faction's bronzes but they are better. No zeal. They'll still be better.
Special mention to
renegade mage, who for some reason does the same as the 3 damages for 1 easy condition 3 point cards in every other faction (wild hunt hound, nauzicaa brigade, lyrian landsknecht, wardancer... with 1 less provision
