CS Game Terminology - Resource Card
From Unstable Games Wiki
Resource cards are also found in the Main deck and allow you to add additional Resources to your Resource Pool. To use a Resource card in your Spell Book, move that card to the discard pile, then add the corresponding Resource tokens to your Resource Pool. Using a Resource card does not cost an Action point. Keep Resource cards in your Spell Book until you are ready to spend them, keeping in mind that once you use a Resource card, you must spend the Resources before the end of your turn (or else you’ll lose them). To Collect a Resource card, you do not need to spend any Resources, but you must still spend 1 Action point.
