Effectiveness will be the same, especially considering the fact that the "useless Revenant" could have an important special ability.
And an important special ability could be, for example, dealing damage. Then the effectiveness would indeed decrease. But in any case, the special ability is a secondary feature of the city; the main thing for the citizens is the daily execution. Here, I didn't see any adequate versions from you.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
