You have to just temper your expectations for Boons, really, and keep careful track of the contents of the deck. There’s only 12 cards, and it does not take long for you to know exactly how likely it is that you’ll get a card that gives you more money or increases your search space.
I would have liked a little more consistency out of the Boons, maybe have two that give +Buy or two that trash, or something, but it’s not the end of the world usually.
The important thing is, most cards that do Boons either give you some other benefit you’re really playing it for (Tracker, Bard), or give you several Boons so you spend more of the game knowing what you’ll get (Fool). There’s Pixie which doesn’t do a lot but it’s a $2 cantrip so you really don’t care. Finally there’s Blessed Village which has enough flexibility to be a fantastic source of Boons on Buy.
Meanwhile a lot of Hex cards just don’t do a lot other than hex, so hexes kind of need to be stronger. Skulk gives you an extra Buy, Werewolf doesn’t do anything else when Hexing, and that one card that isn’t Torturer but means the same thing as that just gives you a little money. I
