I personally think that a Norman deck should be running Eureka, Foresight, Parallel Wills, and Scrying because there's just so much synergy between those cards and his ability. That said, it won't always be possible but you would be able to get around Harbinger if you ever caught it in a scry or parallel wills - make sure to Eureka when you know it's in the top 3 cards and name it with Foresight ahead of time (per FFG it looks like for Foresight and "Search and Draw" effects they want the timing window to be prior to the search part). If it gets to the top of your deck normally you can't Foresight it since it prevents itself from being drawn, but if you can draw it from inside your deck that bypasses the limitation and Foresight cancels it before the Revelation effect would put it on top of your deck.
That said, if you know it's coming you can also just prepare for it and time the "draw" when you know you can spare the two actions, but that combination of cards does let you skip having to deal with that and is worth noting I think.
