Might as well tough both sides, your husband does go for too many terminals. Terminals are generally actions that do not provide a +action, thus they end the actions you can play for that turn (assuming no +action). So if you do grab too many terminals, they often collide, making one of them useless. In practice, that means those woodcutters are your 3rd and 4th terminals. His deck would have been much more competitive if they were silver (essentially compare all purchases < 6 to silver).
