Decoy is a must.
If on private land and you have scouted well, a blind will work but if you have to move then it gets to be a pain and possibly costs you a bird by the noise and movement setting it up.
Set up the decoy/s in a position that you are partly screened by brush or a tree and can draw when the turkey is hidden would be the best advice I can give.
Good Luck
