Never used one for deer but I think a blind out in the open they would be suspicious, should probably be brushed up. I also would think you still have to worry about scent on and in the blind. I have heard of people closing all the windows but one so the scent would not drift out to the deer.
I have used them to film and hunt out of, had deer come within in 10 feet from the blind you dont move and scent they will go right by like they said a little camo around them makes the deer not so spooky

I was being lazy towards the end of a morning last turkey season. It was almost quitting time (noon) and I was in a pop-up blind. I was contemplating pulling my decoy when I heard a shaking sound behind me. I said to myself, only one theing sounds like that. I heard a turkey walking next to the blind, and a scratching sound. a jake strutted into view. the scratching sound was his wings scraping against the tent. He went out to the decoy and screwed around for 10 minutes b4 he lost interest. Seems like neither deer or turkey pay the blinds much attention. I do brush in the blinds.
