I'm sure this has been asked and answered but I can't find it. If I have a card and the effect says decrease a type of production but I don't have that production at the moment. Can I still play it?
Thanks in advance
You always need to perform all effects on a card to be able to play it. (se exceptions in the rules) You need to lower your production if the card says so, or you can't play the card.
This means that you sometimes need to play some cards giving you the production you need to get other cards out..
