A decoy might work during the rut, but where I live, if you tried to use a decoy in rifle season, all you would end up with is a decoy full of holes.

The deer decoys are real, live, deer!

Hunt the food source, find out where the does are hanging out and hunt where you see lot's of does.
When the rut starts - where the girls are - so too will the boys be!

I try to stay away from bedding areas. You also want to stay away from places that deer uses as a sanctuary. Let them have some places where they can run and hide during the day and catch them when they are traveling to the fields in the evenings and coming out of the fields in the morning.

If you can find a patch of hardwoods full of producing white oaks and a large amount of acorns on the ground, that would be your best bet for success.
