I have been blessed with many deer since I bought my present flintlock rifle, and ALL were shot from a ground position. I don't do tree stands...well at least I've never done them yet....
Read The Still Hunter by Theodore S. Van Dyke. Some find his writing style a bit tedious, but he teaches stealthy movement, and learning how the deer spot you and flee, and how to avoid those actions. Plus wind direction. I don't use a cover scent and I use period clothing, and I still get deer, and quite close.
I've hunted from a ground blind, in a vineyard, and in the woods.
The ground blind is a bit of hedge. It breaks up my outline. In the woods I move super slow, paying attention to the wind direction, and plan my movement from large tree to large tree, as I stop for several minutes or longer at the base of these trees to help break up my outline. Also to prevent me from making rhythmic noises.
It's my observation that it isn't a the sound of single twig breaking that bothers the deer as much as the rhythm of the sound of several steps, or they spot you because you're moving too fast.
I don't use scent block or other commercial scents, but I do ensure my outer layer of hunting clothes smell of wood smoke. I have been more successful with this than without, and it may be superstition.
If my clothing gets a bit stinky, when I get home I simply turn the hose on the clothes or soak them in a bucket. Really bad stains might get some plain, lye soap, but never anything that has a modern scent on it. then I suspend the clothing in the smoke from a wood fire after the clothes are line dried.
IF a deer creeps up on me before I can get set, I don't make eye contact with it but keep my head lowered, or if it got really close, I stare at the ground until it takes a step or two to walk away.
The closest that I've shot deer is 3 yards; the farthest is 110 yards. Most have been at about 40-60 yards. At that range they probably aren't going to spot me as long as the wind is right...but the one at 3 yards I was surprised it didn't hear my heart thumping I was so worked up. Apparently my clothing cleaning procedures work...but I'll take luck too...
Finally, ignore the experts that say deer go nocturnal after the first few days after opening day, and that they don't move in the middle of the day...., especially where it's cold or cold & damp. Deer have only one real way of keeping warm, and that's food, and the colder it is the faster they burn calories, so they have to refuel. There is only so much plant fodder they can hold, it takes time for them to gather that by eating, and it takes time for that to turn into heat, so they often move in daylight no matter what day it is in the season. Especially where there are enough hunters to crowd them a bit, as these hunters often leave at mid-day to get some lunch, AND because they've been taught deer don't move except at dusk and dawn. Well the deer froze in place when everybody arrived just before dawn and tromped around. They stayed put without feeding because the woods had a lot of odd smells, and most of the folks that arrived aren't as quiet as they need to be. Then between 11:00 - 1:00 there was this large exodus, and the deer heard that....and by about 2 p.m. the deer are pretty hungry, and it's much quieter and most of the odd smells left with the hunters who went to lunch...they start to creep around to get food, cautious, but hungry, after 12 noon for those reasons.
So..., Hunt all day; take something to nibble on, and stay put....because just after lunch time, but before the 4 p.m. rush of the other hunters coming back to get a shot at dusk, the deer will probably move...be ready
