Mattock says each time you get a reed or stone 'from an action space' you can get a clay.
If I have a card that gives me reed when an action space is used that otherwise would not give me reed or stone, is Mattock triggered?
Specifically, I think Mattock should trigger when Forest Reviewer comes into play (when Grove or Forest is used when the other is occupied, get a reed). Other cards that are less complicated (that don't trigger on opponent actions) should be more straightforward to give the mattock bonus.
