I bought this a few days ago and used it for solo play. They look very nicely done and I’m happy with the purchase.
I first hesitated because I find them a little bit pricey. On the other hand I think independent creators deserve fair wages for good work, and those cards are good work.
I made some handwritten remarks on it to have it better suited for my needs. I hope the creator continues to extend the cards and adds more oracle features to it. For instance, an NPC reaction, NPC morale, story twist subject/action/mood (borrowed from Loner RPG), etc. would be also nice to have on it.
Cheers. Those cards have the potential to fully replace your dice.
