On the concept of the "Schroedingers Draw" as Ozle said, perhaps it is possible to use this in the future, as opposed to trying to calculate the benefit of it before you play it. What I mean by this, is say you have perfect memory, and you know exactly every card in your deck, and every card in your discard pile at all times. Is it possible to gain a benefit to cards being in your discard over cards being in your deck. With cards like chancellor, it can be. So the question I would pose, is that in the example that smithy "can help your next hand but on average doesn't," does the smithy actually on average help your next hands when you have cards like chancellor? Intuitively I would say that more sift is helping chancellors, because you have more information about what cards are in your discard, however I would be hard pressed to come up with any math to prove it. (I think it would really be awesome if chancellor had potential applications beyond chancellor/stash).
