You need to read and learn what deer need. Cover and depending on how far north in Wisconsin that could mean winter yarding cover.
I would go with a nice mix of old ready to harvest forest some that has been harvested 5 to 10 years ago and some crop land at least 40 acres so plot or crops can be planted to feed the deer.
I look for more than deer habitat too. I like to hunt other game like squirrels, rabbits, grouse and even pheasant's.
I only bought 37 acres depending on how high the water is but is surrounded by several thousands of acres of federal land most people don't want to hunt because of all the cranberry bogs they have to deal with to get to dry land.
