But, Professor Birch's Observations does offer card-draw diversity which I've found to be helpful when I do not want to disrupt my opponent's hand (so, no Judge nor N) or dump my hand (i.e., Professor Sycamore) containing other valuable resources. Just nice to have another card-draw option when needed; that's my personal preference.
I agree, but in a deck with scarce resources I could see it being a great supporter. But, in a deck like this i think more often than not Sycamore is more consistent and much better.
N or Judge is there to help you out in situations like you stated. But, every deck can have tough choices and get stuck. Its simply the nature of the game.
Consistency is key? Yes?
