Decoys work great, however, they don't work everytime. I have had toms literally come running and stop 60 yards out, go into a full strut and not come any closer. If you want to really get your heart going, get a tom running at you from 150 to 200 yards away. I have had luck with decoys when hunting a small open field. The gobblers can see the decoys as soon as they enter the field, and they almost immediately start coming my way. I would say the hardest part of decoys is getting that gobbler to go the last 10 yards you are going to need him to take in order to get a good shot.
