Unnamed Action-Reserve: "You may" is unnecessary, as "up to" includes zero.
Craftsman: +Buys come before +
, not the other way around.
Materials: +Cards come before +Actions.
Sheep: This is extremely weak. It's way too dependent on its reaction effect.
I know that correcting the ordering of vanilla bonuses seems nitpicky, but not only does it look better in the proper order (in my opinion, at least), but it also protects your cards against being misread. I've misread plenty of fan-cards that were supposed to give +Cards and +Actions as not giving +Cards due to having the bonuses in the wrong order, for example.
