I've tested the Bot with a pretty Basic Priest Card Deck with the default Deck-Rule.
It appears to me that the Bot don't really know when and how to use the Northshire Cleric (NC).
I've seen a lot of situations where he could get a lot of free cards by using this card and get some badly needed cards instead of just sitting there with NC in his hand an just waiting for the next turn.

p.s.
This is my first Bot-experience, but i am really amazed about the good work here. Keep it up! :)
