And when you have 0 cards in your hand, and topdeck a card you need to win the game (candy, night maintenance, ect.), you will be very sad. I had that happen before, when I didn't think you needed to put a card on the bottom. Now I'm sad....
You cant have perpetual Prof Birch's every turn. You gotta pay SOME price to get to draw! That was the only saving grace (to keep it from being completely broken) to the holon engine in that most card required a discard.
