fika monster, are you alright with me using your mechanic in my cards?
I attributed you on the card text at the bottom.
EDIT: Nvm. It probably makes attack cards too weak and things like Desperation too strong. It needs a nerf but there's no more room on the card.
EDIT: After thinking about it, I think "unused Action" might just be better actually, since it's less wordy and I see you have other cards like this. I'd still recommend not specifying "Action, not Action card" since you can't really "spend" Action cards anyways, so it should be clear.
I like this card, but the wording is really weird. Just say "if you have at least one Action, you may spend it for +2 Cards" without using the word "unused" or "Action, not Action card"... it should be clear what it means and I think this sort of wording just adds confusion.
I also don't understand the bottom line text. Is above line not enough?
