I found this product to be AWESOME! It's not often I give a glowing review with no problems, but this product does exactly what it's supposed to do, does it well, and looks good doing it.
In my game I use the Karma deck to show the favor of the gods. If the PCs do something that the gods might reward then I give them a card to use at a time that they choose. It gives them a bit of a boost and solidifies the importance of the influence of the gods in my current campaign.
The cards give the PC a bit of a boost, some extra damage, an extra little ability or defense. Not enough to completely unbalance the game or encounter, but just enough to tip the scales in a single combat just enough.
If I had only one critique is that it does seem a bit pricey for what is essentially a medium sized set of cards.
This will be an integral part of the rest of my campaign.
