Hmm ... Well:
Fool - Blanket Reset, yes? In the more recent releases, there are two items that you can buy that remove all a character's Attributes (for one) and Skills (for the other), so this isn't bad. Rarity is pretty good, too.
A couple of the Wheel of Fortune cards are downright nasty, given that you don't give any warnings - Death is pretty harsh for a random item that you buy, for example. And is the first WoF card supposed to not do anything?
... "Death: ...Note: Blessed Arcana cards do not cause pointless fatalities. ..." *Looks up at Wheel of Fortune*

As far as pricing goes, Star and Moon are pretty good; Temperance is
way too expensive for such a common card; Sun is ridiculously cheap (A Large Healing Salve - Heals 100 HP - costs 800 gold and has a 5% chance of being in the shop); Judgment is a tad on the cheap side - Oil of Redemption has drawbacks and is still pricier, for example - but isn't too bad; Justice is pretty cheap for its effects; Magician is a bit overpriced (relative to the other cards).
