I suggest simplifying cards wherever you can, especially the ones with very small text. For example, I would either remove Nurse's ability to return cards to the top of your deck or remove its gain-to-hand ability.
EDIT: On Sisterhood, I would specify either "all your unused Actions" or "any number of your unused Actions". "Each of your unused Actions" seems vague to me; I don't know which you mean. Also I'd go for "all". It's simpler.
Sisterhood itself is a cool effect, though maybe too powerful? The power of +Buy is the power to end the game. I'm not saying it's definitely too strong, I'd just keep an eye on that during testing.
Thank you!
I added return to topdeck ability to Nurse to make it a little better, making it not discard good cards if you reveal more than one. And the gain to hand is to make it good to open with. In terms of funcionality only, not text size, do you think it's too strong with these two features?
Nurse also has two parentheses which don't add instructions, only explanations. I myself think they aren't necessary. I copy the first from Save and the second from Nights gained to hand. I would be happy to remove them if this remotion wouldn't cause confusion. What do you think?
Sisterhood was a
, but I changed due to comments that it would be weak. I agree with you that many +Buys would be powerful at endgame. I think it's better to see tests, like you said. The first version converted all Tokens. I changed it because of Villa and Cavalry, but I still really don't know if these particular cases justify this change.
