A very straightforward question:
could I put (i.e as starting items) a blazon of the eye and a horn of anor on the same charachter? Both can not be duplicated, and both effectively are not. They have an identical effect, but different names, so I guess they can.
That would be a neat +4...
horn of anor and blazon of the eye
Yes, you can. Several decks take vantage of this little trick. Especialy Fallen-Pallando heavily-squatting decks. 
Of course the caharacter bearing the two items must be a non-orc non-troll, since an orc/troll wouldn't benefit from Horn of Anor, according with WH rules.
