Im assuming this is for bodybuilding purposes, thus deadlifts can be a good finisher if you're not concerned about the poundages you're lifting.
You need to form your own opinion on the routine about what your goals are and how you like to train.
For example, my methods on back training.
When bodybuilding I do deads second, after heavy Pull-ups (sets of 5), as this way i get get the most out of both exercises. Usually with dead's first im unable to complete my back workout at 100% due to seeing stars. Then i would finish with 1 or 2 exercises in the higher rep range focusing on repetition timing/negative emphasis/feel blah blah blah etc.
For example
Pullups (3 x 5) Moving max weight focus
Deadlifts (3 x 5)
Back exercise 3 (3 x 10-15) Time under tension focus
Back exercise 4 (3 x 10-15)
